"""Video-side download SETTINGS (isolated).

Persists the video download configuration in video.db's ``video_settings`` KV
table — fully separate from the music ``soulseek.*`` paths so the two libraries
never share a folder or collide. The actual download fulfillment engine (wishlist
→ search → grab) is a later roadmap phase; these endpoints just store/serve the
config the Settings → Downloads tab edits.

Keys persisted here (all under video.db):
  - ``download_path``  : input folder a video download lands in
  - ``transfer_path``  : output folder finished video files move to (video library)

Connection settings that are genuinely SHARED with music (the slskd instance, the
torrent/usenet clients, Prowlarr indexers) are NOT stored here — those live in the
music config_manager and are surfaced on the shared Indexers tab + shared slskd
block (a deliberate shared boundary, since they're one physical resource).
