Claude de46202ab4 Fix 27s call ringing delay: TURN credential mismatch and STUN DNS TTL=0
Two bugs caused ICE candidate gathering to fail and timeout (~27 seconds)
before falling back to direct media on every call:

1. TURN credential mismatch — when TURN_PASSWORD was empty in .env,
   coturn defaulted to "changeme" but the entrypoint auto-generated a
   different random password for Asterisk. Every TURN auth attempt failed
   ("check_stun_auth: user easyasterisk credentials are incorrect").

2. STUN DNS TTL=0 — using the FQDN as stunaddr caused DNS resolution
   that returned TTL=0, making Asterisk cancel recurring STUN resolution
   entirely. Since coturn runs on the same host (network_mode: host),
   rtp.conf now uses 127.0.0.1 which needs no DNS at all.

Also documents the Android Call Integration audio issue (ConnectionService
routes audio through the native telephony path, breaking VoIP RTP).

# ================================================================
# Easy Asterisk - Docker Compose
#
# Usage:
# docker compose up -d # Start everything
# docker exec -it easy-asterisk easy-asterisk # Interactive management
# docker exec -it easy-asterisk vpn-diagnostics # VPN diagnostics
#
# All clients connect via FQDN (TLS) regardless of their network.
# coturn provides STUN (NAT detection) + TURN (media relay) so calls
# work even behind strict firewalls, cellular NAT, or VPNs like Proton.
