The WebRTC gate read only the Frigate config, so an install with no go2rtc candidates showed WebRTC as not configured, even though go2rtc fills in default candidates at startup (including the internal one under the HA app) and WebRTC often worked. Unset candidates now run the connectivity probe first, and only a failed probe reports not configured. The not-configured reason shows as a neutral note that names the setting and says WebRTC is optional, rather than as a red error.
