refactor: Align GeoJSON feature properties with unified schema

Standardize property names across campaign fixtures to match the
shared FeatureProperties interface agreed with Glenn (DietBepis1):

- name -> identifier (avoids collision with FeatureCollection name)
- partner -> partners (string array, supports multiple)
- acreage -> measurement + unitOfMeasure (flexible units)
- watershed -> watershedRegion (more descriptive)
- Add restorationServices (empty array, ready for future data)
- Keep: id, campaign, status, projectType (unique to campaigns)
