Bug 35882: Use template wrapper for accordions: Notices

This patch updates the notices template so that Bootstrap
accordion markup for the notice edit view is generated by WRAPPERs.

To test, apply the patch and go to Tools -> Notices.

- Edit any notice.
- The list of message transport types (Email, Print, SMS) should be
  displayed as before: Collapsible panels where clicking the transport
  type heading expands the corresponding information.
- Confirm that changes to notices are correctly saved.
