Webrtc use RTCIceCandidateInit messages with frontend (#129879)
* Add sdp m line index to WebRtc Ice Candidates * Send RTCIceCandidate object in messages * Update tests * Update go2rtc to hardcode spdMid to 0 string on receive * Update for latest webrtc-model changes * Add error check for mushamuro error * Remove sdp_line_index from expected fail tests * Validate and parse message dict * Catch mashumaro error and raise vol.Invalid * Revert conftest change * Use custom validator instead --------- Co-authored-by: Robert Resch <robert@resch.dev>
