55d01400b0 feat: dynamic units table with localized names via GET /units
- Add units + unit_translations tables with FK constraints on products and ingredient_mappings
- Normalize products.unit from Russian strings (г, кг) to English codes (g, kg)
- Load units at startup (in-memory registry) and serve via GET /units (language-aware)
- Replace hardcoded _units lists and _mapUnit() functions in Flutter with unitsProvider FutureProvider
- Re-fetches automatically when language changes

e1fbe7b1a2 feat: move supported languages to DB table, expose via GET /languages
- migration 013: create languages table (code PK, native_name, english_name,
  is_active, sort_order) with all 12 existing languages seeded
- locale: add Language struct, Languages []Language, LoadFromDB() — queries
  languages table at startup and populates both Supported map and Languages
  slice; existing Parse/FromContext/FromRequest unchanged
- main.go: call locale.LoadFromDB after pool is ready
- gemini/recipe.go: remove hardcoded langNames map, use locale.Languages
  linear lookup for English name in prompt
- language/handler.go: new package with GET /languages handler returning
  active languages list (no auth required)
- server.go: register GET /languages as public route
- Flutter: add LanguageRepository + languageRepositoryProvider that fetches
  /languages from backend
- language_provider.dart: replace const supportedLanguages map with
  supportedLanguagesProvider (FutureProvider) backed by LanguageRepository
- profile_provider.dart: remove supportedLanguages.containsKey validation —
  backend is source of truth; sync any non-empty language from preferences
- profile_screen.dart: use supportedLanguagesProvider for display name and
  dropdown (async with loading/error states)

- Add languageProvider (StateProvider<String>, default 'ru') with
  supportedLanguages map matching backend locale.Supported

  callback; all API requests now carry the current language
- Sync language from user profile preferences into languageProvider
  on every ProfileNotifier load/update
- Add language field to UpdateProfileRequest, serialized as
  preferences.language in PUT /profile
- Profile screen: НАСТРОЙКИ section displays current language;
  edit sheet adds DropdownButtonFormField for language selection

ea11a423e0 fix: prevent GoRouter recreation on auth state change
routerProvider was watching authProvider and returning a new GoRouter
on every status transition (unknown → authenticated). This caused
MaterialApp.router to rebuild the entire navigation tree, which
triggered all data providers to start loading before auth was confirmed.

Switch to refreshListenable pattern: GoRouter is created once,
_RouterNotifier fires notifyListeners() when auth changes, and GoRouter
re-runs redirect using ref.read(authProvider). Add /loading splash route
shown during AuthStatus.unknown so no authenticated screen (and no API
call) is initiated until the stored-token check completes.

a0ebd6cc0b feat: apply iOS-style theme and replace removed color constants
Switch AppColors to iOS system palette (007AFF blue, F2F2F7 grouped
background, separator, label hierarchy) and rewrite AppTheme with
iOS-inspired Material 3 tokens (no elevation, negative letter-spacing,
50px buttons, 12px radii). Replace removed primaryLight/accent references
in recipe screens with primary.withValues(alpha:0.15) and primary.

3d900df15b fix: increase connectTimeout and replace expires_at stored column refs
- api_client.dart: connectTimeout 10s → 60s — Flutter was cancelling
  requests to /recommendations after 10s while the server waited for
  OpenAI, causing 'context canceled' on the server side
- product/repository.go ListForPrompt: expires_at is computed via
  (added_at + storage_days * INTERVAL '1 day'), not a stored column;
  wrap in CTE to reference it by alias in SELECT/ORDER BY
- home/handler.go getExpiringSoon: same fix — use CTE to compute
  expires_at before filtering/ordering by it

612a0eda60 fix: repair recognition — migrate vision model and fix XFile handling
- Replace decommissioned llama-3.2-11b-vision-preview with
  meta-llama/llama-4-scout-17b-16e-instruct (Groq deprecation)
- Use XFile.readAsBytes() instead of File(path).readAsBytes() so
  Android content URIs (from gallery picks) are read correctly
- Add maxWidth/maxHeight constraints to image picker calls to reduce
  payload size
- Increase receiveTimeout from 30s to 120s to accommodate slow vision AI
- Log recognition errors via debugPrint instead of swallowing them
