Subject: [PATCH] make webrtc the default experience (#17188)

## Summary
- make realtime default to the v2 WebRTC path
- keep partial realtime config tables inheriting
`RealtimeConfig::default()`

## Validation
- CI found a stale config-test expectation; fixed in 974ba51bb3
- just fmt
- git diff --check
