feat(projectile): 更新法师火球材质和粒子效果

- 更换火球拖尾和核心材质的着色器为透明渲染模式
- 添加GRABPASS禁用以优化渲染性能
- 调整粒子系统的生命周期、速度和尺寸参数
- 启用粒子系统跟随变换移动功能
- 为火球预制体添加胶囊碰撞体用于触发检测

fix(unit): 优化攻击距离判断逻辑

- 在攻击状态下增加1.0f的距离容差
- 避免目标轻微移动导致攻击状态频繁切换
- 提升战斗体验的稳定性

refactor(character): 调整法师角色缩放比例

- 将法师预制体的缩放从100倍调整为正常比例(1,1,1)
- 更新攻击伤害值从默认值改为90
- 修改攻击持续时间从2秒改为2.4秒
- 切换投射物预设为新的火球预制体
