Add login page styles and refactor authentication views

- Introduced new styles for the login page, enhancing layout and responsiveness.
- Updated the login view to utilize the new styles and improve user feedback for login errors and success messages.
- Removed unused controllers and views related to contact and login functionalities to streamline the codebase.
- Adjusted error message handling in the AuthController for better clarity on password requirements.
