Add chat listener and fix ability height/fall logic

Add a ChatListener and register it to render chat with rank prefixes/colors. Enforce a maximum knockback altitude (MAX_KNOCKBACK_HEIGHT_Y) and block height-restricted ability use in Blitzcrank and BlackPanther; surface a localized height_restriction message. Add per-kit noFallDamage tracking for BlackPanther and Trident and cancel fall damage for flagged players in the KitEventDispatcher. Improve hitsRequired resolution: CustomGameSettings will treat a hardcoded 0 as an explicit cooldown-only value (never overridden) and the ActiveAbility getter now only accepts positive override values. Misc fixes: allow throwable items (potions/pearls) to bypass active-item handling, tighten ninja last-hit tracking, fix kit item drop detection in GameStateListener, tweak tablist prefix/suffix handling, and bump TheWorld ability cooldown from 20000ms to 25000ms. Also update language entries and minor formatting/cleanup.
