- Introduced constants for admin hooks: `STATS_FETCH_LIMIT`, `DEFAULT_PAGE_LIMIT`, and `STATS_REFETCH_INTERVAL` to enhance readability and maintainability.
- Updated query guards to ensure data fetching is restricted to superusers.
- Enhanced accessibility across admin components by adding `aria-hidden` attributes and improving focus-visible styles.
- Simplified `useAdminStats`, `useAdminUsers`, and `useAdminOrganizations` with shared constants.
- Added 403 Forbidden page with proper structure, styling, and tests.
- Implemented new tests for admin hooks, DashboardStats, AdminLayout, and ForbiddenPage for better coverage.
- Replaced `useAuthStore` with `useAuth` from `AuthContext` across frontend components and tests to ensure dependency injection compliance.
- Enhanced E2E test stability by delaying navigation until the auth context is fully initialized.
- Updated Playwright configuration to use a single worker to prevent mock conflicts.
- Refactored test setup to consistently inject `AuthProvider` for improved isolation and mocking.
- Adjusted comments and documentation to clarify dependency injection and testability patterns.
- Refactored `useIsAuthenticated` and `useCurrentUser` to use `useAuth` from `AuthContext` instead of `useAuthStore`.
- Updated test setups to inject `AuthProvider` with mocked store hooks for improved test isolation and consistency.
- Replaced legacy `useAuthStore` mocks with `AuthContext`-compatible implementations in affected tests.
- Implement comprehensive tests for `ProfileSettingsForm`, `PasswordChangeForm`, and `SessionCard` components to validate rendering, interactions, and state handling.
- Add tests for session management hooks (`useSession`, `useRevokeSession`, and `useRevokeAllOtherSessions`) to verify logic and API integration.
- Ensure coverage of edge cases, error handling, and success callbacks across all new tests.
- Implemented comprehensive tests for `useAuth` hooks (`useIsAuthenticated`, `useCurrentUser`, and `useIsAdmin`) with mock states and coverage for edge cases.
- Added tests for `AuthGuard` to validate route protection, admin access control, loading states, and use of fallback components.
- Updated `.gitignore` to exclude `coverage.json`.
