Fix POI distance calculation reliability for remote/Celery execution

- Fix silent log loss: replace hardcoded "uvicorn.error" logger with __name__
  in osrm_client, otp_client, poi_distance_calculator, and poi_tasks (uvicorn
  logger has no handlers in Celery worker, so all errors were silently dropped)
- Add Celery retry: autoretry_for=(Exception,), max_retries=3, retry_backoff
- Add top-level exception handling in task with full traceback logging
- Fix upsert_distances: replace session.merge() (PK-based) with proper
  dialect-aware INSERT ON DUPLICATE KEY UPDATE / ON CONFLICT DO UPDATE
- Filter out listings with null/zero coordinates before routing
- Raise OSError when all routing engines fail with 0 results computed,
  distinguishing "nothing to compute" from "all engines unreachable"

- Fix OSRM client to use semicolons (not commas) for source/destination
  indices in /table API requests. Commas caused "Query string malformed"
  errors for any batch with more than one origin.
- Add error handling in poi_distance_calculator for unreachable routing
  engines (OSRM/OTP). Connection failures now log an error and skip the
  mode instead of crashing the entire Celery task.

Add self-hosted routing clients and distance calculator

RoutingConfig loads OSRM/OTP URLs from env vars. OSRM client uses the
/table endpoint for batch NxM distance matrices (walk/cycle). OTP client
uses GraphQL API for transit routes. POI distance calculator orchestrates
both, skipping already-computed distances and reporting progress.
