Remove stunaddr/turnaddr from rtp.conf — fixes STUN timeout causing 27s delay

Asterisk doesn't need STUN/TURN in rtp.conf for this setup because:
- It already knows its public IP via external_media_address in pjsip.conf
- Its RTP ports are port-forwarded, so host ICE candidates are sufficient
- stunaddr/turnaddr caused STUN gather timeouts (~27s) on every call,
  whether pointing at the FQDN (DNS TTL=0 bug) or localhost (UDP timeout)

coturn is for SIP *clients* behind strict NAT — they configure TURN in
their own app settings, independently of Asterisk's rtp.conf.

ICE support remains enabled so Asterisk participates in ICE negotiation.
