feat:Add app category display to Dev Center interface (#1033)

Add app category display to Dev Center interface (#1033)

• Updated the main app list to include a category label/badge next to each app name
• Handled undefined or empty categories by displaying "Uncategorized" or omitting the label
• Added category field to individual app settings page, with real-time update after category changes
• Ensured consistent UI and styling for category display across both the main list and settings page
• Improved alignment and spacing for category labels to match existing app metadata layout
• Updated app data structure to support category metadata in the app objects

Testing:

• Verified category display in app list
• Tested category updates in settings
• Ensured graceful handling of apps without categories
• Checked responsiveness and UI layout on different screen sizes

hi @mariatouil thanks again for looking into this issue. This is not a complete implementation. For example, category is not shown in an app's settings page. Also, categories in app list are pushing the quick links for each app out of view (i.e. 'settings', 'add shortcut to desktop', etc)
