Fix ~790 basedpyright errors across the test suite:
- Type stub subclasses of real production classes with super().__init__()
- Add missing generic type arguments and Dict[str, Any] annotations
- Add None guards before subscript/member access
- Adapt tests to production API changes (removed dead handlers,
PersistentModelCache.get_default, _i18n_filter_added location)
- Add enable_civarchive_api toggle (default on) to allow disabling
CivArchive to avoid its rate-limit windows entirely
- Add metadata_provider_order dropdown with two presets:
CivitAI → CivArchive → Archive DB (default) and
CivitAI → Archive DB → CivArchive
- Wire both settings through backend (metadata_service, settings_manager,
misc_handlers) and frontend (SettingsManager, state, settings modal)
- Reorder Metadata section in settings modal: toggles → status/management
→ fallback order, for natural top-down workflow
- Make update_metadata_providers() log the effective provider chain
using actually-registered providers rather than settings assumptions
- Add 5 test cases covering all provider-combination paths
- Complete i18n translations for 6 new keys across all 9 non-English locales
Add RateLimitRetryingProvider and _RateLimitRetryHelper classes to handle rate limiting with exponential backoff retries. Update get_metadata_provider function to automatically wrap providers with rate limit handling. This improves reliability when external APIs return rate limit errors by implementing automatic retries with configurable delays and jitter.
