Fix Command Zone graphics/logic layers separation

1. CommandZoneMenu: Changed to take PlayerGraphicsItem* instead of
     PlayerLogic*, accessing logic via player->getLogic()

  2. Removed getCounterWidget() from PlayerLogic;
     method already exists correctly in PlayerGraphicsItem

  3. PlayerMenu: CommandZoneMenu, fixed signal
     connection to use player->getLogic() for commandZoneSupportChanged

  4. AbstractCounter: Connects to CounterState::activeChanged signal,
     removing direct graphics calls from PlayerEventHandler

  5. CommandZone: Explicit tax counter registration via registerTaxCounter()
     with auto-cleanup, replacing childItems()/dynamic_cast iteration

  Also fixed PlayerActions to query CounterState instead of AbstractCounter
  for proper layer separation.
