Add a queue-count badge to the macOS player controls queue button
(MacOSControlsSectionRenderer) and the shared mini player queue button
(MiniPlayerView), matching the iOS pill button behavior.
The mini player buttons set NavigationCoordinator flags, but only the
iOS tab views hosted the corresponding sheets. Host QueueManagementSheet
and PlaylistSelectorSheet on the macOS root view, bound directly to the
coordinator flags.
Also wire the add-to-playlist button in the full macOS player controls:
add the missing .addToPlaylist case to MacOSControlsSectionRenderer and
thread onShowPlaylistSelector from the expanded sheet layouts through
MacOSPlayerControlsView to the existing playlist sheet host.
Render the macOS control bar button row and top bar from the active
preset's sections via a new MacOSControlsSectionRenderer, replacing the
hardcoded QuickTime-style rows in MacOSControlBar. Add a keepOnTop
button type and macOS-specific button availability lists, and adapt the
player controls settings editors (preset editor, section editor, button
configuration) for macOS.
Also apply the preset font style to the control bar time labels, and
update the built-in macOS Default preset order (queue before transport,
fullscreen at the end), bumping builtInPresetsVersion to 7.
