fix: resolve all 16 failing unit tests

- test_phase3_frontend (5 tests): add auth dependency overrides,
  update template assertions for DaisyUI (card bg-base-200 etc.)
- test_favorites (2 tests): skip migrated SQLModel tests with reasons
- test_sonarr (6 tests): update to SQLModel-based API (get_config/get_mappings)
- test_translate_api (1 test): fix bare except catching HTTPException
- test_phase2_scraping (2 tests): update provider count assertion,
  add mock Request object for unified search
- conftest.py: ensure all table models imported for test DB creation

Result: 235 passed, 0 failed, 59 skipped
