Tatlatat 3885f9fa90 STT: clean temp audio files on transcription failure ...

STTService._transcribe_local writes the audio to a NamedTemporaryFile
(delete=False) and only unlinks it on the success path, before the except.
If model.transcribe() raises (corrupt audio, model/runtime error, etc.) the
function logs, returns None, and leaves the .webm temp file behind — so
every failed local transcription leaks a file in the system temp dir.

Initialize tmp_path = None up front and move the unlink into a finally
block so the temp file is cleaned up whether transcription succeeds or
raises.

tests/test_stt_leak.py stubs the whisper model to raise during transcribe,
runs _transcribe_local, and asserts it returns None and leaves no new .webm
file in the temp dir. Fails before this change.
