Adapt custom actions panel for declarative layout system

Convert the ObjectPermission detail view to use the new panel-based
layout from #21568. Add ObjectPermissionCustomActionsPanel that
cross-references assigned object types with the model_actions registry
to display which models each custom action applies to.

Also fix dark-mode visibility of disabled action checkboxes in the
permission form by overriding Bootstrap's disabled opacity.
