feat: import Seed (mycantaloupe.com) data — 1,655 assets enriched

- Added import_seed.py — reads Machine List(8).xlsx, matches by Asset ID → machine_id
- 51 new columns on assets table (route, barcode, sales, contact info, etc.)
- seed_data table with full 62-field JSON per asset for detail enrichment
- Seed data card in frontend asset detail view
- GET /api/assets/{id} now returns result.seed and result.seed_imported_at
- GPS columns from Seed ignored per request
- 1,654 matched, 199 unmatched (Seed-only assets not in MSFS)
