Issue:

RN-1545: Epic datatrak sync

---

Note

Adds a new sync-server and shared sync utilities to enable offline-first Datatrak syncing via streaming APIs and a local PGlite DB, updates clients/types/infrastructure, and bumps key deps.

• Sync Architecture:
  • New @tupaia/sync utilities (snapshotting, lookup, stream framing) and sync-server microservice with streaming sync endpoints and scheduled tasks.
• Datatrak Web (offline-first):
  • Local DB via PGlite + DatatrakDatabase, ModelRegistry in-browser, ClientSyncManager, and new Sync/Database context providers.
  • New client sync routes and stream helpers; queries/mutations adapted to use local DB (offlineFirst) with server sync.
• Database/Models:
  • Add sync tables/models (sync_session, sync_queued_device, sync_device_tick, sync_lookup, tombstone) and lookup-table population.
  • Expose toggle tombstone triggers in tests; move model typings to @tupaia/tsmodels.
• Shared Libraries:
  • Server-boilerplate supports stream/pipe routes; server-utils adds StreamMessage, file helpers, ScheduledTask refactor.
  • Types/constants expanded (sync enums/requests, updated_at_sync_tick across models); new task filter utilities.
• API Servers:
  • datatrak-web-server adds sync endpoints; entity-server filters via @tupaia/tsmodels helpers.
• Infrastructure:
  • Nginx config and PM2 updated to host sync-api; build/deploy scripts include sync-server.
• Dependencies:
  • Upgrade express and date-fns; add polyfills/plugins for browser DB/Node APIs.

Looks like @tupaia/datatrak-web is missing these dependencies:

• case (used in ./src/sync/insertSnapshotRecords.ts), and
• knex (dev dependency used in ./src/database/DatatrakDatabase.ts)
