…illing STTMetrics.audio_duration accumulated only the duration of audio frames pushed to the Deepgram WebSocket via the PeriodicCollector. Deepgram bills for the full WebSocket connection lifetime, so cost-tracking users saw a consistent 4–5 s per-stream undercount against Deepgram's usage reports (much worse on short calls). Track the connection open timestamp and the total duration already reported via _on_audio_duration_report, and on close emit any remainder between wall-clock connection lifetime and reported frames. The collector is also flushed before the remainder calc so pending frame duration is accounted for first. Fixes livekit#5498
