fix: mobile responsiveness for all admin pages

- DataTable: overflow-x-auto on table wrapper (affects users, rooms, tickets)
- Radio: overflow-x-auto wrappers around all 3 tables (shouts, applications, schedules)
- Catalog items: responsive grids (grid-cols-1 sm:grid-cols-3) in Add/Edit dialogs
- Catalog tabs: TabsList overflow-x-auto for narrow screens
- Import clone: pagination flex-wrap to prevent overlap on small screens
