[Eco Bounty] Depinscan Missing "Close" (X) Button in Developer Config Modal

Description: When accessing the "Config" tab within the "Team Projects" section of DePINscan.io on a mobile device, there is no "X" or "Close" button available to exit the configuration view or return to the previous menu. This creates a "navigation trap" where the user must use the browser's back button or refresh the page to exit.

Environment:

• Website: depinscan.io/developer/settings/team-projects

• Device: Mobile (Android/Chrome Browser)

• Section: Developer Settings > Project Config

Steps to Reproduce:

1. Log in to the DePINscan Developer portal on a mobile device.

2. Navigate to Settings > Team Projects.

3. Open a project to view the Config tab.

4. Try to find a way to close the settings view without using the system back button.

Expected Result: There should be a visible "X" button in the top right corner of the modal or tab header to allow users to easily dismiss the configuration screen.

Actual Result: The top right corner of the header is empty (as indicated by the arrow in the screenshot), leaving the user with no intuitive way to close the section.
