Subject: [PATCH] tapes: make serving kind-aware (video vs frame backing store)

get-tape now returns kind ('zip'|'mp4', default 'zip') + mp4Status. The
/media/tapes/<code> redirect picks .mp4 for video-backed tapes and .zip for
frame-based ones (explicit .mp4/.zip on the request still wins). Missing kind
defaults to zip, so all existing frame tapes resolve exactly as before. Step A
of camera-roll video -> !tape (video-backed tapes).
