Retranscribe feature: ponovi STT z drugim providerjem v Edit modalu

PROBLEM: STT (Soniox/Scribe) včasih popolnoma narobe slišije besedilo —
npr. 'BILA JE LJUBEZEN PRVA' postane 'BILAL JO ME ZANPRLA' (TRIO ŠUBIC).
Edit modal je do zdaj zahteval popoln recut z novim clip range.

NEW: '🔁 Ponovi transkript' gumb v Edit modalu z dropdown za provider:
  - Scribe (ElevenLabs) — default, najboljši za nemščino + slovenščino
  - Soniox — slovenski default v auto routing
  - Whisper local (faster-whisper)

Backend:
  POST /api/jobs/{id}/retranscribe { provider, auto_upload?, lang? }
  - Briše stari MP4 + analysis.json + .srt + .ass (lokal + S3)
  - Re-queue job z whisper_provider override
  - Ohrani isti clip range — analyze.py si naredi svežo analizo
  - retranscribe_count števec za sledenje poskusov

UX: confirm dialog → 1.5s status → auto-close modal → watchJob za live progress.
Brez auto_upload v Nextcloud — preveri rezultat preden re-uploadaš.
