ui: click-to-target via nameplate hit testing

Browse source 
Left-clicking anywhere within a nameplate's bounding box (name text +
health bar) calls setTarget() for that unit. Uses manual mouse position
hit testing since nameplates are drawn on the background DrawList rather
than as ImGui widgets. Click is ignored when ImGui has captured the mouse
(e.g. when a window is open).
