Overview:

• The user_api has been updated to comply with the new UI requirements.
• A new feature has been added to engine.js in the main_app for displaying error messages to users.

Modifications:

Main Application

• Introduced showError(errorMessage, buttonText, buttonOnClickFunction) to enable error message display to users along with actionable steps.
• A new error display div has been added to base.html in the body section, equipped with a text area for the error message and a button for user action.
• Error messages have been added to the renew_token response.
• Resolved all issues related to token_renewal.
• Updated the searchUsers function in the main_app to use the appropriate endpoint.

User Application

• The user authentication system has been refined to skip 42API authentication for GET requests.
• Implemented a strategy for handling username conflicts in the user_api, assigning alternative usernames to new users.
• Modified the URL patterns for the user_api.

• /api/users/ to retrieve all users.
• /api/user/<int>/ to access a specific user.
• /api/search/<str>/ for user search functionality.

issue fixed.

Remove the use of port 3000

I can't replicate the issue. also I checked the code and token.js is only getting injected once. so I'm not sure how to replicate it or if it's even possible.

This happens when I leave the tab idle for a while, the expiry is detected correctly but not sure if the last part is supposed to be there.
