This branch implements the feature to make custom tabs behave like the "Posts" tab, allowing vals in custom tabs to be viewed in the swipe viewer.

1. ValGrid Component:

   • Updated to support swipe viewer for both "Posts" tab and any custom tabs
   • Added logic to only exclude "code" tab from swipe viewer functionality

2. ValGridItem Component:

   • Modified to handle link URLs differently based on tab types
   • Added special handling for code tab items to always link directly to Val Town
   • Improved UI indicators to show when swipe view is available

3. Project Refactoring:

   • Created a new ProfileTabs.tsx component to extract tab navigation and content functionality
   • Split UserProfile.tsx code into smaller, more maintainable components
   • Added proper tab switching functionality within components

Custom tabs now have the same behavior as the "Posts" tab:

• When clicking on a val in a custom tab, if it has a proper URL (from moiConfig or httpEndpoint), it will open in the swipe viewer
• Users can swipe through all vals in that custom tab
• This maintains the existing behavior of the "code" tab, which still links directly to Val Town

• Verify that custom tabs show the swipe viewer when clicking on vals
• Confirm that swipe navigation works within custom tabs
• Check that the "code" tab still links directly to Val Town pages
• Test that "View All Code" button works correctly when a custom tab has no content
