feat: automatically transcribe when ASR active on receiver

[matthiasn]

This PR adapts the speech recognition such that when on the creator, auto transcribe was disabled and it is enabled on the receiver side, the ASR using Whisper will start automatically. This is in particular a scenario where ASR is disabled on mobile, where it might use too much battery.
