fix(mini-player): show action buttons on macOS too

The custom titlebar was rendered only on Win/Linux, so macOS users had
no way to toggle the queue, pin-on-top or expand back to the main
window — the native macOS titlebar takes care of dragging + close, but
those three actions live entirely in app code.

Render a slim transparent in-page strip on macOS as well, holding just
the queue / pin / maximize buttons right-aligned. Close is omitted on
macOS since the red traffic light already does that.
