playlist cards on the watchlist tab now get the same hover cog → the per-channel
settings modal (custom show-name + quality override). the modal is kind-aware so
it reads 'Playlist settings' + 'the playlist's real name'.
no backend change needed: playlist videos are wishlisted with channel_id =
playlist_id, so the existing get/set_channel_settings + enqueue override lookup
already key off the playlist id. UI-only: cog on playlistCard + data-kind passed
to openChannelSettings(id, title, kind). test covers both cogs.
hover a channel on the watchlist Channels tab -> a settings cog appears (mirror
of the unfollow x) -> opens a self-contained modal:
- Show name (folder): overrides the $channel folder/show-name token; blank uses
the real channel name.
- 'Force a specific quality' toggle -> resolution/codec/container/60fps/HDR
override; off = use the global youtube quality from Settings.
VideoYoutube.openChannelSettings(id, title) builds the modal, loads via GET, saves
via POST /youtube/channel/<id>/settings. .vyt-cset-* CSS. string-contract test.
(note: 10 pre-existing soundcloud music-orchestrator test failures are unrelated
to this work — they fail on a clean HEAD too.)
