Add ability feedback/particles; refactor kits

Introduce centralized AbilityFeedback and AbilityParticles utilities and update language strings. Refactor IceMage: replace old snowball mechanics with an aggressive Ice Spike Burst (cone projectiles, cooldown tracking, config keys) and a defensive snowball barrage with metadata; reorganize config accessors and passive behaviors. Refactor Ninja: add layered sounds/particles for teleport, rewrite smoke aura as an animated BukkitRunnable with visual rotation and enemy effects, and improve lifecycle/scheduling handling. Update en_US.yml with new kit item names, passive labels, and messages.
