Hide cart for admin users and remove confirmation from view-only modals

Admin Cart Visibility:
- Hide cart icon/badge in mobile header for admin users
- Cart was already hidden in desktop sidebar
- Admins don't need to purchase products

Modal Confirmation Improvements:
- Removed confirmation from AdminOrders detail dialog (view-only)
- Removed confirmation from AdminMembers detail dialog (view-only)
- Kept confirmation on AdminProducts form dialog (has form inputs)
- Kept confirmation on AdminEvents form dialogs (Event and Block forms)
- Kept confirmation on AdminConsulting meet link dialog (has form input)

This prevents annoying confirmations on simple view/close actions while
still protecting users from accidentally closing forms with unsaved data.
