feat: make chest particle type and color configurable per rarity

[Copilot]

Chest particle effects (UNCOMMON/RARE/EPIC) were hardcoded to Particle.DUST with fixed colors. This adds full configurability for both particle type and color per rarity level.

Settings (config.yml → world.chest-particles)

chest-particles:
  uncommon-particle: DUST       # any Particle enum name, or NONE to disable
  uncommon-color:               # only used for DUST-type particles
    ==: Color
    ALPHA: 255
    RED: 255
    GREEN: 255
    BLUE: 0
  rare-particle: DUST
  rare-color: ...               # default: white
  epic-particle: DUST
  epic-color: ...               # default: fuchsia

Implementation

• Settings.java — adds 6 @ConfigEntry fields (3× String particle names + 3× Color). Getter/setter pairs are String↔String for Java Beans compatibility with BentoBox's YAML reflection system (mismatched types cause IntrospectionException that silently nulls the entire settings object). Resolution to Particle enum happens via:

  • resolveChestParticle(Rarity) — parses the string, returns null for "NONE" (disables particles for that rarity), falls back to DUST on invalid names
  • resolveChestColor(Rarity) — returns the configured Color for the given rarity

• BlockListener.fillChest() — replaced hardcoded color/particle logic with calls to the two resolve methods; non-DUST particles are spawned without DustOptions (color is irrelevant to them).
