InputPopover

A thin wrapper over Mantine Popover with the dropdown look of the composer pickers (ModelPicker, ModeSelector). Use it for your own toolbar controls in InputBar leftActions or rightActions so they match. The trigger element's own onClick still runs and then toggles the dropdown; a non-element trigger is wrapped in a span. It works controlled (open and onOpenChange) or uncontrolled (defaultOpen). side and align map to Mantine positions (top and start by default, so it opens above the composer), sideOffset sets the gap. The dropdown renders in a portal, so it is not clipped by a narrow widget.
