Smittix fce66a6a60 Fix DMR audio stream failing with "no supported source found"
Digital voice is intermittent — dsd-fme only outputs PCM during active
voice transmissions. Without input, ffmpeg never wrote the WAV header
and the browser got an empty response. Add an audio bridge thread that
feeds 100ms silence chunks during voice gaps so ffmpeg always has input
and the browser receives a continuous WAV stream. Add auto-reconnect
on the frontend if the audio stream drops while the decoder is running.
