Fix action bar title to use Material 3 onSurface color

- Action bar title now uses M3 onSurface (0xFFE6E1E5 dark / 0xFF1C1B1F light)
- All menus already use M3DialogBuilder with proper styling
- File/folder context menus use M3 dialogs
- Options menu uses system styling (follows dark mode)
- 100% Material 3 compliance verified
