- Removed `window.__TEST_AUTH_STORE__` logic for E2E test store injection in `AuthProvider` and related comments.
- Updated `AuthInitializer` to clarify E2E test behavior with mocked API responses.
- Streamlined `AuthContext` handling by prioritizing explicit `store` prop or production singleton.
- 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.
