feat: import Kuchnia Wikinga catering deliveries into the food bank

Pulls the day's delivered dishes and their real per-portion macros out of
panel.kuchniavikinga.pl, so a catering meal is one keypress instead of five
retyped numbers.

A delivered meal is not an eaten meal, so nothing is ever logged unattended:
dishes land in the *curated* bank, and entries are written only after an
explicit confirmation. Auto-logging would let the gate satisfy its own
checkpoint from a delivery note, and would record what the courier dropped off
rather than what was eaten.

Three surfaces:
  - `diet-guard kuchnia [--log] [--yes]`
  - the lock screen's "Today's delivery" button, which prefills the meal form
    dish by dish (the user still clicks Log & Continue)
  - a warm-up after each logged meal, on the existing background thread

All event-driven; no new systemd timer. The two automatic paths go through
`refresh_delivery_once`, guarded to one fetch per day.

The panel is an undocumented white-labelled Dietly API; the endpoint map was
recovered from its JS bundles and confirmed against live responses. Notes,
including the traps, are in docs/kuchnia-wikinga.md.

Load-bearing details:

* Macros are per portion and `weight` is that portion in grams -- proven, not
  assumed: 4P+4C+9F reproduces the stated calories within ~1% on every meal of
  the captured day. `_energy_is_consistent` re-runs that check per dish and
  drops any that fails; a per-100g mix-up is invisible in a payload and would
  silently skew every logged meal by a factor of several.
* `bank_dishes` compares nutritional fields before calling `add_manual_entry`,
  which restamps `t` unconditionally. Without the compare, every refresh
  republishes the whole curated bank to every peer. Tests assert on call count.
* Duplicate log suppression reads today's synced log, not a local marker:
  `log_meal` mints a fresh uuid, so a re-import after marker loss would merge
  as duplicates on every peer.
* The gate hook is in `on_focus_ready`, not `_cli_gate._should_lock`:
  `gate_is_due()` never reads the food bank, so a refresh there could not
  change the lock decision while adding a third-party round trip to the ~105ms
  `gate --check` fast path.
* `requests` is lazy-imported so the gate's not-due tick does not pay for it.
* Credentials and the cached session cookie live in ~/.config/diet_guard at
  mode 600, outside the synced tree. The credentials file is written by hand,
  never by the package -- the same contract as sync_token.

`_GateDashboard` is merged into `_GateMealFlow`, and both "pull it in from
elsewhere" flows share one `_PullFlows` mixin: pylint's max-parents counts
every MRO entry, so the gate's controller chain had no room for a new class.

Also adds a side-by-side row for the two pull buttons -- stacking them cost
42px and pushed the tab past the viewport at 1366x768.

+
+Modelled on :mod:`diet_guard._gatelock_fetch`, but it cannot reuse
+:func:`~diet_guard._gatelock_fetch.start_fetch`: that is typed

+worker would reintroduce exactly the cross-thread state that module's docstring
+exists to forbid, so the pattern is copied rather than bent:
+
+* **The worker touches no widget.**  Tcl is not thread-safe, and that includes
+  ``after`` -- the worker only ``put``s on a queue, and a poll scheduled on the
+  Tk thread picks it up.  That also makes the completion path testable with no
+  thread at all: put a result, call the poll, assert.
+* **The worker always feeds the queue**, even if the call raises.  It has
+  nowhere to propagate to, so an escaping exception would leave the poll
+  waiting forever with the button disabled and the user stuck behind the lock.
+* **Daemon thread**, so a hung request can never keep the process alive after
+  the window is gone -- the gate is a ``Type=oneshot`` unit and must exit.
+
+Nothing here logs anything.  The fetch only *offers* dishes; writing entries is
+a separate, explicitly confirmed step (:mod:`diet_guard._kuchnia_log`).

+Three calls, and the shape of the walk is not what the endpoint names suggest:

+2. ``company/customer/order/{orderId}`` -> the order, which **embeds every

+was confirmed against three separate delivery days.  The menu endpoint is keyed
+by the opaque ``deliveryId``, never by the date.

+# Kuchnia Wikinga catering import
+
+Pulls the day's delivered dishes — with their real per-portion macros — out of
+`panel.kuchniavikinga.pl` and into diet_guard, so a catering meal is one
+keypress instead of five retyped numbers.
+
+## What it does, and deliberately does not
+
+**A delivered meal is not an eaten meal.** Dishes land in the *curated* food
+bank; entries are only ever written after an explicit confirmation. If the
+importer logged automatically, the gate would satisfy its own checkpoint from a
+delivery note, and the log would record what the courier dropped off rather than
+what was eaten — skipped, shared and binned meals included.
+
+So:
+
+- **`diet-guard kuchnia`** banks the day's dishes and prints them. Nothing is
+  logged.
+- **`diet-guard kuchnia --log`** asks first (`--yes` skips the prompt for
+  scripting).
+- **The lock screen's "🍱 Today's delivery"** button *prefills* the meal form,
+  dish by dish, in the caterer's own meal order. The user still clicks
+  "Log & Continue" for each.
+
+## The API (undocumented, recovered by inspection)
+
+The panel is a white-labelled **Dietly** React SPA. There is no published API;
+the endpoint map was recovered from its Vite bundles and confirmed against live
+responses on 2026-08-22. Re-check if the bundle hashes change.
+
+| | |
+|---|---|
+| Base | `https://panel.kuchniavikinga.pl/api` |
+| Login | `POST auth/login`, **form-urlencoded** `username=…&password=…` |
+| Session | a `SESSION` cookie — **not** a bearer token |
+| Headers | `company-id: kuchniavikinga` (the company *name*), `X-Launcher-Type: BROWSER_PANEL` |
+
+The walk is three calls:
+
+1. `company/customer/order/active-ids` → `[orderId]`
+2. `company/customer/order/{orderId}` → the order, which **embeds every
+   delivery** with its date. No enumeration call needed — but `deliveryMeals`
+   carries ids only, no names and no macros.
+3. `company/general/menus/delivery/{deliveryId}/new` → the actual menu.
+
+Three traps worth knowing before touching `_kuchnia_orders.py`:
+
+- **`.../deliveries/{id}/details` does not work.** It 404s (400 keyed by date),
+  verified against three separate delivery days, despite being the obvious name
+  and the one the bundles pass a `deliveryId` to. The menu endpoint above is
+  the one that answers.
+- **`deliveryId` is opaque, never a date.** The date form 400s.
+- **No `XSRF-TOKEN` cookie is issued**, so the CSRF echo the panel's own
+  JavaScript performs is a no-op here. The client skips it when absent rather
+  than sending an empty header.
+
+### Macros are per portion
+
+`nutrition` = `{weight, calories, protein, carbohydrate, fat, dietaryFiber,
+sugar, salt, saturatedFattyAcids}`. **`weight` is the portion in grams and the
+macros are totals for that portion**, which maps straight onto diet_guard's
+`grams`/`kcal`/`protein_g`/`carbs_g`/`fat_g`.
+
+This was proven, not assumed: 4·protein + 4·carbs + 9·fat reproduces the stated
+`calories` within ~1% on every meal of the captured day, and the day totals
+2055 kcal against the plan's declared 2000.
+
+`_kuchnia_parse._energy_is_consistent` re-runs that check on every dish and
+**drops any that fails**. A per-100 g/per-portion mix-up is invisible in a
+payload and would silently skew every logged meal by a factor of several, so
+the parser refuses rather than importing a plausible-looking lie.
+
+## Credentials
+
+Two files under `~/.config/diet_guard/`, both mode 600, both **outside** the
+synced tree — a password and a live session cookie must not travel to another
+device.
+
+```bash
+install -m 600 /dev/null ~/.config/diet_guard/kuchnia_credentials
+printf '%s\n%s\n' 'you@example.com' 'your-password' \
+  > ~/.config/diet_guard/kuchnia_credentials
+```
+
+`kuchnia_credentials` is **written by hand and never by the package**, the same
+contract as `sync_token`. `kuchnia_session.json` caches the session cookie so a
+refresh normally skips the login round trip; it is created `touch(mode=0o600)`
+*before* it holds anything, then atomically replaced — writing and chmod'ing
+afterwards would leave a live cookie world-readable for the duration.
+
+Missing or unreadable credentials are not an error at the call site: the fetch
+returns a reason string and the caller carries on.
+
+## Triggers
+
+Three, all event-driven. **No new systemd timer** — `diet-guard-sync.timer` was
+deliberately deleted and `install.sh` actively uninstalls it.
+
+| | Where | Guarded? |
+|---|---|---|
+| CLI | `diet-guard kuchnia` | no — an explicit ask always goes and looks |
+| Gate | `MealGate.on_focus_ready` → `_autoload_delivery` | yes |
+| After a meal | `_cli_log.cmd_ate`, on the existing background thread | yes |
+
+The guarded pair go through `refresh_delivery_once`, which skips the walk when
+today has already been fetched (`kuchnia_last_import`, one ISO date). Without
+it the after-log hook would pay a login plus three requests after *every* meal.
+Only a clean fetch records the date, so an outage is retried.
+
+**Why the gate hook is in `on_focus_ready` and not `_cli_gate._should_lock`:**
+`gate_is_due()` reads only the food log and the schedule, never the food bank,
+so a catering refresh there could not change the lock decision — while adding a
+third-party round trip to the ~105ms `gate --check` fast path, which opens no
+window at all. Hooking it once the window is up puts the spinner *inside* the
+lock instead of in front of it. An automatic fetch is also silent about bad
+news: it must not talk over the prompt telling the user which slots to fill.
+
+## Things that will bite
+
+- **Re-banking unchanged dishes floods sync.** `add_manual_entry` restamps `t`
+  unconditionally and the merge derives each record's clock from it, so a
+  refresh that re-banks everything republishes the whole curated bank to every
+  peer. `bank_dishes` compares the nutritional fields first. Tests assert on
+  **call count** — "the entry exists" passes while this misbehaves.
+- **Imports go to `food_bank_manual.json` only.** The derived bank is rewritten
+  from the log on every meal, so anything written there vanishes.
+- **Duplicate log suppression reads today's log, not a marker.** `log_meal`
+  mints a fresh uuid per entry, so a re-import after a lost marker would merge
+  as duplicates on every peer. Matching `desc`+`slot` against the synced log is
+  robust to marker loss *and* correct across devices.
+- **`requests` is lazy-imported.** The gate's not-due tick imports the CLI and
+  must not pay ~78ms for an HTTP stack it never touches. Call sites reach
+  through `sys.modules[__name__]` so `patch.object` still wins.
+- **The phone needs no importer.** It receives the curated bank and the log
+  through existing sync, and `FoodBankRecord.fromJson`/`toJson` enumerate a
+  fixed key set — a provenance field written by the PC would be silently
+  dropped on every round-trip, producing an endless re-add/re-strip ping-pong.
+
+## Re-probing the API
+
+`scripts/probe_kuchnia.py` (login, order walk) and
+`scripts/probe_kuchnia_details.py` (which URL form serves a day's meals) dump
+redacted JSON captures. Run the first, then the second. They prompt once and
+cache the session, and credential/cookie *values* never reach the dump.

+"""Capture the Kuchnia Wikinga panel's API shape so the importer can be written.
+
+The panel (``panel.kuchniavikinga.pl``) is a white-labelled *Dietly* React SPA
+with no published API.  Its endpoint map was recovered by grepping the Vite
+bundles, which settled the URLs, the auth scheme and the header set -- but not
+the *response shape*.  This script fetches the real payloads so
+``diet_guard._kuchnia_parse`` can be written against captured JSON instead of
+against a guess.
+
+It lives in ``scripts/`` rather than as a ``diet_guard`` subcommand on purpose:
+the package carries a 100% branch-coverage gate, and a probe inside it would
+need tests written against the very payload it exists to discover.
+
+Three questions the capture must answer, because each changes the mapping code:
+
+* **Are macros per portion or per 100 g?**  The highest-risk unknown -- a
+  per-100 g figure stored as a portion total silently under-reports every meal.
+  Look for a weight/grams field next to ``calories``.
+* Are the macro fields on the meal object, or nested under something like
+  ``nutritionalValues``?
+* Does the order object embed its deliveries, or is a separate call needed?
+
+Nothing here writes to ``diet_guard`` state; the only output is a JSON dump.
