Automerge docs created before the tags schema don't have the field.
The migration runs 5s after startup (after loadAllDocs completes),
patches missing tags onto events, and assigns known demo event tags.
Also removes debug endpoint and tracing logs.

Implement the 4-layer data model (device → encrypted backup → shared sync → federated):
- Extract shared encryption-utils from community-store (deriveSpaceKey, AES-256-GCM, rSEN format)
- Encrypt module docs at rest when space has meta.encrypted === true
- Fix relay mode persistence: relay-backup/relay-restore wire protocol + .automerge.enc blob storage
- Add backup store + REST API (PUT/GET/DELETE /api/backup/:space/:docId) with JWT auth
- Add client BackupSyncManager with delta-only push, full restore, auto-backup
- Wire backup stubs in encryptid-bridge to BackupSyncManager
- Add rspace-backups Docker volume
- Create docs/DATA-ARCHITECTURE.md design doc with threat model and data flow diagrams
