feat(video): add video upload with remux/transcode playback

Add video as a media kind in photos: streaming upload with per-kind limits, ffprobe metadata, poster frame reusing the image variant pipeline, and a playback object (remux when web-compatible, else h264/yuv420p/aac transcode). Video jobs run on a separate pool with a long lease. Frontend gains a video viewer, grid badge/duration and video upload.
