Three code paths could fire yt-dlp immediately (polite=False) while a
download was already running, causing YouTube to see two simultaneous
authenticated sessions and invalidate the cookie:
- search.py: live yt-dlp fallback now skipped while any download is active
- downloads.py: _ensure_video uses polite=True so it waits for active
downloads to finish before fetching metadata for an unknown video
- channels.py: follow_by_url uses polite=True when fetching metadata
for a brand-new channel
Added is_download_active() helper to ytdlp.py to expose the active
download state without importing private globals.

Writes a Kodi/Jellyfin-compatible .nfo XML file next to each .mp4 on
download completion, deletes it when the download record is removed, and
exposes POST /api/downloads/nfo/generate to backfill NFOs for existing
downloads. Frontend adds a "Generate NFO" button in the Downloads header.

- fetch_available_subs() queries yt-dlp for manual + auto-generated
subtitle langs available on YouTube for any given video
- GET /api/videos/by-yt/{ytId}/subs exposes this to the frontend
- DownloadRequest now accepts subtitle_langs to override the global
setting on a per-download basis
- Watch page fetches available subtitle langs on load (in parallel),
shows a CC dropdown with manual langs + auto-generated langs labeled
"(auto)"; selected lang is passed through to the download

- auto-sync daemon: background thread checks every hour and syncs followed
channels for users with sync_interval_hours set (6/12/24h options)
- disk stats: /api/stats now returns total/used/free/download bytes;
Stats page shows a disk usage bar
- subtitles: subtitle_langs setting (e.g. "en,sv") passed through all
download paths; yt-dlp writes .srt files alongside the video
- Settings page: sync interval dropdown + subtitle languages input
