fix: use ingest HTTP API instead of direct Postgres for VPS telemetry; cache speedtest results per interface

- hub/server.py: replace psycopg2 Postgres connection with urllib HTTP call to
  ingest /api/devices endpoint (fleet Postgres is Docker-internal, not reachable
  from the VPS directly)
- telemetry-synology.sh: run_speedtest() now writes per-interface cache files
  (speedtest-result-<iface>); _cached_speedtest() reads cache if < 35 min old;
  _collect_wan() uses cached result so throughput shows in telemetry without
  blocking every 1-min cycle
