Per-channel "skip auth check" toggle for the youtubetab warning

Browse source 
yt-dlp prints a scary-looking ERROR when it can't confirm a channel
tab loaded authenticated:

  ERROR: [youtube:tab] @Channel: Playlists that require authentication
  may not extract correctly without a successful webpage download…
  pass "--extractor-args youtubetab:skip=authcheck" to skip this check

For PUBLIC channels that's just noise — there's no auth-gated content
to miss, and the flag silences it without changing which videos are
found. But for members-only/private channels archived with cookies,
the warning is a real "your cookies may not be working, you might be
getting an incomplete list" signal worth keeping.

So make it a per-channel toggle rather than a blanket setting:

- DownloadOptions gains `skip_auth_check: bool`; apply() emits
  `--extractor-args youtubetab:skip=authcheck` when set. (Its own flag;
  the youtubetab: namespace is distinct from the POT provider's
  youtubepot-bgutilhttp: one, so they coexist.)
- Desktop + web channel-options dialogs gain a checkbox with a tooltip
  spelling out the public-vs-private trade-off.

1 new test; 81 pass.
