feat: asset naming, location extraction, and location display

- New asset naming: {MID} - {Customer} / {Address} / {Building details}
- Extracted 660 building_names from customer data (Disney resorts, hotels)
- 1,704 assets now have location data (building_name, floor, etc.)
- Location section in detail view now shows building, floor, trailer, room
- Added has_gps filter to API for map loading
- Added location_source column to track GPS origin
