- Consolidated and modularized `eslint.config.mjs` with defined rules for source, test, E2E, and scripts.
- Improved test and E2E rules with relaxed settings for flexibility and enhanced mocking.
- Standardized variable naming and removed redundant imports in unit and E2E tests.
- Updated error handling and comments to align with modern TypeScript best practices (e.g., `@ts-expect-error`).
- 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.
- 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`.
