feat(storage): add resources tab and improve S3 deletion handling

Add new Resources tab to storage show page displaying backup schedules using
that storage. Refactor storage show layout with navigation tabs for General
and Resources sections. Move delete action from form to show component.

Implement cascade deletion in S3Storage model to automatically disable S3
backups when storage is deleted. Improve error handling in DatabaseBackupJob
to throw exception when S3 storage is missing instead of silently returning.

- New Storage/Resources Livewire component
- Add resources.blade.php view
- Add storage.resources route
- Move delete() method from Form to Show component
- Add deleting event listener to S3Storage model
- Track backup count and current route in Show component
- Add #[On('submitStorage')] attribute to form submission
