feat(parcel-sync): sync-first architecture — DB as ground truth

- Rewrite export-bundle to sync-first: check freshness -> sync layers -> enrich (magic) -> build GPKG/CSV from local DB
- Rewrite export-layer-gpkg to sync-first: sync if stale -> export from DB
- Create enrich-service.ts: extracted magic enrichment logic (CF, owners, addresses) with DB storage
- Add enrichment + enrichedAt columns to GisFeature schema
- Update PostGIS views to include enrichment data
- UI: update button labels for sync-first semantics, refresh sync status after exports
- Smart caching: skip sync if data is fresh (168h / 1 week default)
