- scripts/start-voip.sh: updates DNS then docker compose up
- update-dns.sh: supports --once flag, runs locally with curl
- All CF API calls forced to IPv4 (-4 flag)

- update-dns.sh: detects public IPv4/IPv6, upserts CF records
- Runs on container start + every 5 minutes
- Only updates if IP actually changed (skips if unchanged)
- python:3-alpine container with curl
