Give the menu-bar hint popover an explicit size so it actually shows

NSPopover measures its content when show() is called, and a container sized
only by Auto Layout constraints has no frame to report yet, so show() failed
silently and the hint never appeared. The label and container now carry
explicit frames, and the view controller states its preferredContentSize.
