Add comprehensive tests for authentication, settings, and password reset pages

- 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.
