- 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`).
- Introduced smoke tests for Login, Register, Password Reset, Password Reset Confirm, and Settings pages.
- Enhanced test coverage for all dynamic imports using mocks and added Jest exclusions for non-testable Next.js files.
- Added component-specific test files for better structure and maintainability.
- Improved test isolation by mocking navigation, providers, and rendering contexts.
