Add Login Screen with Redirect to Dashboard

[Kom02]

Description:

Implement a login screen that appears as soon as the user opens the website. The user must authenticate before accessing any other part of the application. Upon successful login, the user should be redirected automatically to the dashboard.

Purpose:

A login screen ensures that only authenticated users can access the platform, enhancing security and providing a clear entry point for user sessions.

Acceptance Criteria:

• A login screen is displayed as the first page when the site is accessed.
• Users are required to log in before viewing any other content.
• After a successful login, users are automatically redirected to the dashboard.
• If a user is already logged in (authenticated session), they are taken directly to the dashboard on subsequent visits.
• The login process handles incorrect credentials with clear error messages.
• The login screen is responsive and works on all device sizes.

Additional Information:

Consider using existing authentication methods (such as email/password or Stellar wallet authentication) as appropriate for the platform's security requirements.

Priority:

Low
