The CallDecoder now inspects each incoming packet's codec_id and
automatically switches the audio decoder if it differs from the
current profile. This enables cross-codec interop where one client
sends Opus and the other sends Codec2 — previously the receiver
would try to decode with the wrong codec, producing garbled audio.

Enables debugging Codec2 by allowing forced codec selection from CLI.
Supports: good, degraded, catastrophic, codec2-3200, codec2-1200.
Frame size, timing, and jitter buffer are all adjusted dynamically
based on the selected profile.
