Move backup configuration from separate app to forgejo folder:
- Move forgejo-backup-cronjob.yaml to apps/forgejo/
- Move forgejo-backup-secret-sealed.yaml to apps/forgejo/
- Add backup-namespace.yaml to ensure backup namespace is created
- Remove apps/backup/ folder
- Remove apps/app-backup.yaml Argo CD application
This consolidates the backup configuration into the main Forgejo
application, eliminating the need for a separate Argo CD app.
