video download panel: per-format actions (video/audio) + select mode

Reworks the download model around a format choice (video = ReClip video, audio =
audioOnly) instead of a global "extract audio" toggle:

- Input phase is just URL + Fetch (dropped the audio checkbox).
- Each card tracks video + audio download state independently and shows a button
  per format (Video only when ReClip reports video formats — audio-only sources
  get just Audio).
- Playlist top actions: "All video" (when any item has video), "All audio", and
  "Select".
- Select mode: each card shows Video/Audio checkboxes (pick one, both, or none per
  item); a "Start download (N)" button runs the chosen set and shows a fake
  progress bar (N/M count, no real byte progress). Bulk "All video/audio" reuse
  the same progress bar.
- Single item = large card with the two format buttons, no bulk row.

VideoInfo gains `formats` so the client can tell video-capable from audio-only.
