j.foucher 5b3a11a733 ConvAgent: agent audio multicast back to Reliable (fix Opus crackle/gaps)

Sending Opus over Unreliable multicast caused missing words and crackling:
Opus is a stateful inter-frame codec, so a dropped or reordered packet
desyncs the decoder and corrupts all following frames until the stream
resets. Unreliable was originally adopted only to stop a reliable-buffer
overflow — but that overflow came from 32-152KB raw-PCM RPCs (pre-Opus).
With Opus + sub-chunking each RPC is ~2KB (2-3 partial bunches) at
~1.25 RPC/s, so the 512-bunch reliable buffer stays in single digits and
cannot overflow. Reliable restores ordered, lossless delivery.

- MulticastReceiveAgentAudio: Unreliable -> Reliable.
- Keep the 40-frame (0.8s, ~2KB) sub-chunking — it is what keeps packets
  small enough for Reliable to be safe.
- Harden the raw-PCM fallback (only reached if Opus init fails): hard-cap
  one message at 320KB and drop the tail so it can never overflow the
  reliable buffer, and warn on every fallback (config bug: [Voice]).
