fix: add storage deletion with library cleanup and scan validation

- Delete storage config now properly removes related libraries and media
- Scanner validates storage config exists before starting cloud scan
- Prevents orphaned scans when storage is removed
- Added repository methods: DeleteByType, FindByID for storage config
- Remove unused storageHandler route to fix compilation
