feat: update session cookie options and enhance authentication flow

- Changed SameSite attribute for session cookies from 'strict' to 'lax' to allow cross-origin fetches, improving compatibility with various client requests.
- Updated cookie clearing logic in the authentication route to use `res.cookie()` for better reliability in cross-origin environments.
- Refactored the login view to implement a state machine for managing authentication phases, enhancing clarity and maintainability.
- Introduced a new logged-out view to inform users of session expiration and provide options to log in or retry.
- Added account and security sections to the settings view, allowing users to manage their account and security preferences more effectively.
