L5: dock-panel button refinements — overflow menu, tooltips, opposite-mode tag buttons

Top-bar rare-capture variants move to a right-anchored More popup; short faces gain hover-delay full-name tooltips (prefix stripped); bottom bar becomes four opposite-mode Item/Track tag buttons + Show Both (Toggle/Activates dropped); wider cluster gaps. New pure overflow_menu/mode_enable/tooltip modules, CTest-covered. Same actions, same contract.
