[client/idd] audio: prevent recording transport stalls

Browse Source 
Give microphone data priority over replaceable clock feedback and
reduce feedback traffic on the shared client-to-host FIFO.

Retry short FIFO stalls outside the realtime thread and coalesce
consecutive packets in the existing fixed Windows buffers.

Avoid one broker write per tiny PipeWire quantum without adding
allocations or intentional capture latency.
