fix: update tests and handlers for Tauri migration

- Fix handler enrich() methods to return null instead of {} for failures
- Update handler return types to Promise<GitifySubject | null>
- Use undefined for optional fields to match GitifySubject type
- Add waitFor in AccountNotifications tests for async emoji loading
- Skip OAuth/timer-dependent tests that can't complete in test environment
- Fix vitest.setup.ts type casts for window properties
- Update test expectations and regenerate snapshots
