youtube playlists: same settings cog/modal as channels

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.
