ZGaetano e9e883d06e fix(deltacast-bridge): flush queued audio backlog to live edge on reader attach
The ~2.5s of leading silence at record start was the VHD audio slot QUEUE: while
the recorder is idle (no FIFO reader), the bridge blocks on open(O_WRONLY) but the
board keeps buffering audio slots. When the record ffmpeg attaches, the bridge
streamed that stale backlog first — heard as leading silence and pushing audio
out of alignment with the live video.

On each reader attach, drain slots that lock FAST (already-queued backlog) and
stop at the first lock that takes ~a frame period (= waiting on a live slot), so
the reader is handed the live edge, A/V aligned.
