Introduce client-side trap presets and a visual "trigger reveal" for traps, plus related entity/renderer changes.
- AbilityTrap: add TrapPreset enum and applyTrapPresetDefaults; wire a SubGuiTrapPresetSelector hook to apply presets from the GUI; pass visibility into created trap entities.
- EntityAbilityZone: add visible flag, TRIGGER_FLASH_STATUS state, setEntityState usage to notify clients of triggers, handleHealthUpdate to start client-side flash, and adjust construction/serialization accordingly.
- RenderAbilityZone: implement trigger-reveal visuals (revealFade, triggerReveal) that briefly show a burst when traps trigger, skip rendering for invisible traps unless revealing, and tweak flash/timing logic.
- Minor cleanup: remove/condense comment blocks and refactor noisy helpers across AbilityZone/AbilityHazard, plus language entry update and new SubGuiTrapPresetSelector GUI class.
These changes enable preset application for traps and improve client-side feedback when traps trigger.
