4grayandClaude Opus 5 fc81f4f941 fix(playlist): bound playlist downloads and isolate startup auto-update (#1233)
Playlist downloads in the main process ran without an axios timeout, so a
host that accepted the connection and then went silent kept the request
pending forever. The startup auto-update refreshed playlists sequentially,
so that one unresponsive source also withheld every playlist that did
refresh, and the URL import dialog could spin with no way out.

- Add PLAYLIST_FETCH_TIMEOUT_MS (30s) to the main-process fetch and reuse it
  in the refresh worker instead of its duplicated literal. Redirects are
  followed one hop at a time, so each hop is bounded separately.
- Move auto-update into playlist-auto-update.ts and refresh at most
  AUTO_UPDATE_CONCURRENCY (3) playlists at once, isolating each failure while
  preserving the requested order. An unbounded fan-out would download and
  parse arbitrarily many large M3U files in the main process at once.
- Redact refresh log URLs, which routinely carry Xtream username/password
  query parameters.

The existing auto-update spec handed out fixtures by call order, which no
longer holds once refreshes overlap; it now keys them by source type.

Fixes #931
