feat: add bookmarks sidebar to Debug page

Added ThreePaneLayout to Debug page so bookmarks are visible:
- Debug page now has same layout as other pages
- Shows bookmarks sidebar on the left
- Debug content in the main pane
- Can compare centralized app bookmarks with Debug bookmarks side-by-side

This makes it easy to verify that centralized bookmark loading
works the same as the Debug page implementation.
