test: add useProviderActions hook unit tests
- Add comprehensive tests for provider CRUD operations:
* addProvider: trigger mutation correctly
* updateProvider: update provider and refresh tray menu
* deleteProvider: call delete mutation
* isLoading: track all mutation pending states
- Test Claude plugin integration sync logic:
* Conditional sync based on app type (claude vs codex)
* Integration toggle handling (enabled/disabled)
* Error handling with custom/fallback messages
* Official vs custom provider category detection
- Test usage script save functionality:
* Update provider meta and invalidate cache on success
* Display error toast with custom/fallback messages on failure
- Mock React Query mutations, Tauri API, and toast notifications
- Fix TypeScript spread operator issues in mock definitions
- Cover all success/failure paths and edge cases
Test Coverage:
✓ 12 test cases covering provider actions
✓ Plugin sync: 5 scenarios (app type, toggle, errors)
✓ CRUD operations: add, update, delete
✓ Usage script: save success/failure
✓ Estimated 95%+ code coverage
