Add taunt button, Tab as Escape alternative, free cam Q/E removal

- OverviewMenu: taunt button (manual ping + close, hider/seek-only), Tab triggers the Escape chain (TypingGuard-gated)
- GameModeManager: LocalPlayerIsHider helper, allow E-ping in free cam (Q/E no longer used for movement)
- FreeCamController: vertical movement only via Space/Ctrl
- Icons: Icon_taunt (wired), Icon_firstperson_paint (unwired, for later)
