feat(storage): group backups by database and filter by s3 status

Group backup schedules by their parent database (type + ID) for better
organization in the UI. Filter to only display backups with save_s3
enabled. Restructure the template to show database name as a header with
nested backups underneath, allowing clearer visualization of which
backups belong to each database. Add key binding to livewire component
to ensure proper re-rendering when resources change.
