Remove unused features; fix reminder false alarms; share all state
Four asks, plus the fixes two review passes turned up.

Removals (all unused):
- "Repeat last meal" button, and the reward/temptation-bundling prompt it
  was the sole trigger for. Replaced with a post-log progress card showing
  kcal against budget, macros, and the adherence streak.
- The multi-item meal builder, on both the gate and the phone. The stored
  `components` field stays: nothing writes it now, but historical composite
  entries and the food bank still read it and it is part of the wire format.
- Meal photos entirely: 13 files, `imagePath`, the photo filter, the
  wrapper's /blobs/ route, image_picker, and the CAMERA permission.

Reminder false alarms had three real causes, all fixed:
- Logging never reconciled notifications, so a reminder sat on screen up to
  15 minutes after the meal was logged -- on the phone itself.
- The background check never pulled, so a PC-logged meal nagged forever
  until the app was opened. Now mirrors _cli_gate._should_lock: cheap local
  check, network only when a slot looks due, then re-check.
- Meals before 08:00 / after 22:00 were attributed to no slot at all. New
  slot_for_log/slotForLog clamps them to the first/last slot, byte-identical
  across Python and Dart. Deliberately separate from elapsed_slots, which
  would otherwise make every slot fall due at 23:00.

Budget history, so lowering the budget stops rewriting the past:
- Forward-only (effective_from, kcal) entries; each day is judged against
  the budget in force then. Verified live: setting 2000 left a 36-day
  adherence streak and the whole calendar pixel-identical.
- Rides as hist:<date> fields on the existing budget record. crdt_sync
  merges per-field over the union of field names and both devices push the
  merged log, so a device that predates the feature relays them untouched --
  no coordinated rollout, no second document.
- The seed guard tests emptiness, not file presence: _sync can write an
  empty history after merging with a pre-feature peer, and a presence check
  would then never seed again, silently reclassifying every past day.

One shared source of truth for every piece of data:
- Body weight now travels as its own `weight` CRDT field. Inside `value` it
  was collateral damage of whole-map LWW -- any phone budget edit deleted it,
  and the protein target with it.
- Both halves of the food bank sync. The curated half (foods added without
  eating them) was the last device-local state. The derived half merges with
  count as the clock, so LWW means max-count-wins; the log stays
  authoritative for membership, because a CRDT union never shrinks and a
  peer's stale copy would otherwise resurrect a deleted food permanently.
- Bank adapters honour tombstones, and Dart parses bank records defensively:
  a cast failure there is an Error, not an Exception, so one malformed
  remote record would have broken phone sync permanently.

_test_guard.py blocks any pathlib write to real user state while pytest is
in the process, whatever conftest is loaded. A throwaway test run outside
the package conftest destroyed a real GitHub token during this work; this
makes that class of accident impossible rather than merely discouraged.
