fix(engine): prevent stock-tap from toggling HUD on Android

Every draw-from-stock tap was also firing the HUD auto-hide toggle
because the stock pile is not an ActionButton and toggle_hud_on_tap
had no way to know the tap was consumed by game logic.

Add GameInputConsumedResource(bool): handle_touch_stock_tap sets it
on TouchPhase::Started when a draw fires; toggle_hud_on_tap checks
and clears it on TouchPhase::Ended, treating it as equivalent to
started_on_button so the HUD stays put.
