+-- Migration 018: record whether an uploaded file carried a video track (ADR-033,
+-- amended 2026-10-01).
+--
+-- A Teams meeting with the camera off is still an .mp4 with a video track, so video
+-- files are ACCEPTED: only the audio is extracted and the video is discarded. This
+-- flag lets the transcript page say so — "this file contained a video track; only its
+-- audio was used" — so the user is never left to wonder what happened to the picture.
+-- It outlives the job: completing or failing an upload does not clear it.
