feat(fight_boss): 优化BOSS战斗奖励逻辑并修复宠物等级突破100级限制

重构了handleMapBossFightRewards函数，将奖励逻辑分离到独立的处理函数中，
增加了shouldGrantBossWinBonus条件判断，确保只有满足条件时才发放胜利奖励。

同时修复了宠物等级系统，允许宠物等级突破100级限制但面板属性仍保持100级上限，
改进了经验获取和面板更新逻辑。

fix(item_use): 添加全能性格转化剂使用验证

添加了UniversalNatureItemID常量定义，增加对道具ID和性格配置的有效性验证，
确保只有正确的道具和性格类型才能被使用。

refactor(fight): 统一战斗结束原因处理逻辑

引入normalizeFightOverReason函数来标准化战斗结束原因，
统一了不同模块中的战斗结果映射逻辑，提高了代码一致性。

perf(pet): 优化宠物升级和经验计算性能

移除了等级100的硬性限制，在保证面板属性不超限的前提下允许宠物等级继续增长，
优化了经验分配和面板重新计算的逻辑流程。
