- GroupSchedulePrintController used $this->authorize() but Laravel 13's base Controller has no AuthorizesRequests trait — switched to Gate::authorize()
- Added deleteGroup() to GroupList with full cascade: sessions (attendance auto-cascades), schedules, enrollments, waitlists, then the group itself
- Delete button with wire:confirm for Arabic confirmation prompt, gated behind groups.delete permission
