Added RTC configuration with Google's public STUN servers to enable
peer-to-peer connections across different networks (e.g., WiFi to
cellular data).
Changes:
- Created drop/rtc_config.json with 5 Google STUN servers
- Updated drop/compose.yaml to mount RTC config file
- Added RTC_CONFIG environment variable pointing to config file
This should resolve connectivity issues when devices are on different
networks or behind NAT.
