1e201acbdc Split _sync.py and its tests; extract the gate fixtures from conftest
_sync.py 498 -> 165, into siblings that each own one concern:

  _sync_client.py  picking a backend and building the remote store
  _sync_banks.py   pull/merge/push for the food bank and the budget
  _sync_paths.py   the kuhyx/syncs wire layout, shared by both
  _sync_errors.py  SyncError, so _sync and _sync_client need not import
                   each other

The patch targets moved with the code they guard, which is the whole risk of
this commit. unittest.mock.patch and monkeypatch.setattr both bind to a
*module object*, so a patch left pointing at _sync after CONFIG_FILE and
SYNC_TOKEN_FILE moved to _sync_client redirects nothing. That is not
hypothetical here: the first run of the suite took 9m18s instead of 7s and
raised 401s, because tests were reaching the real GitHub API with a fake
token. Repointed:

  conftest       SYNC_TOKEN_FILE, CONFIG_FILE      -> _sync_client
  test_sync*     GitHubSyncClient (30 patch sites) -> _sync_client
  test_backend   mirror/firebase_client_for        -> _sync_client

The repo's own _test_guard caught the same leak independently, which is the
behaviour worth keeping: two guards, both fail-closed.

test_sync.py 482 -> 205, splitting the budget and pull/revision classes into
siblings and the shared fakes into _sync_fakes.py.

conftest.py 284 -> 155, moving the Tk/gatelock fixtures to _gate_fixtures.py.
Importing them back is what registers them (pytest_plugins is an error in a
non-root conftest), and they are named in __all__ because ruff's autofix
otherwise deletes the "unused" import and silently disables Tk blocking --
it did exactly that once here. Verified afterwards with a canary asserting
_gatelock.tk is still a MagicMock, not merely that the suite passes.

Verified: 692 tests / 100% coverage unchanged; ~/.local/share/diet_guard
byte-identical before and after the run; cd /tmp && python3 -m diet_guard sync
-> 402 entries, exit 0. Gate 47 -> 44.

diet_guard pushed as "pc" (Python), "phone" (Android) and "desktop" (web).
A role constant collides the moment a second machine takes the same role,
and after a reinstall the new install inherits the previous one's CRDT
identity -- the same reasoning home_inventory already records for choosing a
uuid. Both halves now mint a uuid once and persist it: the PC in
~/.local/share/diet_guard/.device_id, the app under SharedPreferences
'crdt.nodeId' (the key todo and home_inventory already use).

The old constant survives as the legacy id and is passed to sync_log /
syncLog, so devices/<legacy>/ is skipped as this device's own. Without that
every tick would re-download and re-merge this device's own pre-migration
log as though a peer had written it -- idempotent under LWW, but hundreds of
KB, 96 times a day. It drops to None once that path is reclaimed; a test
covers both states, including a negative control proving the skip is the
legacy id's doing.

All four documents move together (food_log, food_bank, food_bank_manual,
budget), and the hist:<date> fields riding on the budget record are
untouched -- merge_record unions field names, so they relay through
unchanged.

The resolver lives in its own module (_device.py / sync_device_id.dart)
because _sync_merge needs it for HLC stamping too and importing _sync there
would be a cycle. Dart resolves it asynchronously at startup, before
LogStorageService.init(); currentSyncDeviceId falls back to the compile-time
role constant until then, so a too-early Hlc stamp gets a valid id rather
than crashing.

conftest redirects the new id file in the same change that introduces it --
without that a test mints a uuid into the real state dir and this machine's
live sync identity is decided by whichever test ran first. Verified by
checking ~/.local/share/diet_guard/ before and after: untouched.

Verified live, not just against mocks: the sync timer ran mid-change and
migrated this machine to f8f46da6. All 358 food_log records and all 100
food_bank records are present under the new path (0 missing vs devices/pc/),
and the new log's HLCs carry only its own id -- confirming it did not
re-merge the old path as a peer.

Python: 687 tests, 100% branch coverage. App: 518 tests, analyzer clean.
Pins bumped to crdt-sync-v0.6.0 / crdt_sync_dart-v0.7.0 (pyproject,
requirements.txt, .pre-commit-config.yaml, pubspec), and the new library is
installed into /usr/bin/python's user site-packages so the production timer
does not ImportError on its next tick.
