zarzet 755c907982 refactor(analysis): move the FFmpeg runner out of the widget
The card ran ffprobe, both FFmpeg sessions, SAF temp copies, the
native spectral-cutoff job and its cancellation inside State. Move that
pipeline verbatim into AudioAnalysisRunner in
lib/services/audio_analysis_runner.dart together with the private
per-run records from the widget's models part, which is now empty and
removed.

The card keeps request ids and every setState. The runner takes a
`bool Function() isCancelled` that the card builds from the same
`!mounted || requestId != _spectrogramRequestId` test, polled at the
same points that used to call _checkAnalysisRequest. cancel() and
dispose() run the jobs invalidate/dispose, network cancel and native
job cancel in the original order.

Subprocess order, temp file names and cleanup, SAF copy and the native
data job payload are unchanged.
