feat: add parcel-sync module (eTerra ANCPI integration with PostGIS)

- 31 eTerra layer catalog (terenuri, cladiri, documentatii, administrativ)
- Incremental sync engine (OBJECTID comparison, only downloads new features)
- PostGIS-ready Prisma schema (GisFeature, GisSyncRun, GisUat models)
- 7 API routes (/api/eterra/login, count, sync, features, layers/summary, progress, sync-status)
- Full UI with 3 tabs (Sincronizare, Parcele, Istoric)
- Env var auth (ETERRA_USERNAME / ETERRA_PASSWORD)
- Real-time sync progress tracking with polling
