Claude 37765f4569 Rewrite coturn service to fix startup crash
Three changes to fix coturn failing to start:

1. Use environment vars instead of mixing Compose interpolation
   (${VAR}) with shell escaping ($$ARGS) in the command - the
   old approach was fragile and could produce broken shell scripts

2. Remove --no-loopback-peers - since Asterisk runs on the same
   host (network_mode: host), coturn must allow relay to localhost
   otherwise it refuses to relay media to Asterisk

3. Health check: redirect output to /dev/null to avoid noise

# ================================================================
# 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.
