Fix: Login and SSO validation not working properly

[Pycomet]

Problem Description

The application needs proper validation for login and other SSO (Single Sign-On) authentication options.

Current Behavior

• SSO options are not properly validated
• Users may encounter authentication issues

Expected Behavior

Affected Components

• Login form
• SSO integration
• Firebase authentication

Acceptance Criteria

• Login form validates user input properly
• SSO options are validated before authentication attempt
• Error messages are clear and helpful
• All edge cases are handled gracefully
• Unit tests cover validation logic
• Integration tests for SSO flows

Additional Context
