Per-folder "Check all" action + DB backup download

Browse source 
Two small follow-ups to the folder hierarchy that round out the
folder-as-a-profile workflow and give the user a one-click way to keep
an offsite copy of their library state.

Per-folder check
- New `POST /api/folders/:id/check` mirrors the existing
  /api/scheduler/run endpoint but scoped to one folder's members.
  Each channel's stored DownloadOptions (quality / rate limit /
  match-filter / extra args) applies just like a scheduled re-check.
  Returns 409 when downloads are already running.
- Web folder-manager modal: each non-empty folder gets a "⬇ Check"
  button next to Rename / Delete. Status line reports the count of
  channels queued.
- Desktop folder-manager window: same — a small ⬇ icon-button per row,
  visible only for folders with at least one member. Same options-
  honouring re-check path as the right-click "Check for new videos"
  action.
- This effectively gives us "Profiles" lite: organize channels into a
  folder, then trigger a batch re-check whenever you want.

DB backup
- New `GET /api/backup/db` reads `<channels_root>/yt-offline.db` and
  streams it back with `Content-Disposition: attachment` so the
  browser downloads instead of rendering. Filename includes the unix
  timestamp so downloads don't clobber. Returns 404 when running in
  in-memory mode (no DB file to dump).
- We deliberately don't bundle config.toml + cookies.txt here:
  config is short to recreate and cookies.txt carries live session
  credentials that shouldn't fly over the wire unprompted.
- Web settings modal gains a "⬇ Download library snapshot" button in
  a new Backup section, with a hint explaining what's covered (watched
  / favourites / bookmarks / waiting / channel-options / folders).

55 unit tests pass.
