fix(parcel-sync): fix [object Object] in address field + re-enrich corrupted

The eTerra API returns street and locality as objects ({name: "..."})
not strings. formatAddress now extracts .name correctly.

Also added:
- streetNumber fallback (alongside buildingNo)
- String() safety on addressDescription
- Corruption check: any enrichment containing "[object Object]" is
  automatically re-enriched on next cycle
