shawn da2a23f6da Inline route optimization into canteen server (remove proxy to daily-route on port 8912) 
- Added extraction DB config and _get_extraction_db() helper
- Added _status_label, _haversine, _solve_tsp (nearest-neighbor + 2-opt)
- Added GET /api/workorders/search (native)
- Added POST /api/workorders/lookup (native)
- Added GET /api/workorders/today (native, reads bookableresourcebooking)
- Added GET /api/workorders/technicians (native)
- Added POST /api/route/optimize (native TSP solver)
- Removed httpx dependency, _proxy_route, _get_route_client
- Removed all proxy endpoints
