fix CloudKit compatibility: default values, optional relationship, background mode

- Add default values to all SwiftData attributes (CloudKit requirement)
- Make memos relationship optional (CloudKit requirement)
- Add allMemos computed property for safe unwrapping
- Add remote-notification background mode for CloudKit push sync
