Subject: [PATCH] Add select/deselect all functionality to multi-event home
 screens

Introduce a `TriStateCheckbox` in both `IntentMultiEventHomeScreen` and `BunkerMultiEventHomeScreen` to allow users to toggle the selection state of all items simultaneously. The checkbox reflects the current selection state (On, Off, or Indeterminate) and updates all individual item checkboxes when clicked.
