feat: 人生事件和剧本收藏从 localStorage 切换为真实 API

- 后端：新增 t_event_favorite 表（UNIQUE KEY + MyBatis-Plus Entity）
- 后端：LifeEventController 新增 /favorite/toggle、/favorite/page、/favorite/check 三个真实端点
- 后端：EventFavoriteService 完整 CRUD，含 toggle/分页/批量查询/状态检查
- 后端：删除旧的 favorite-placeholder mock 端点
- 前端：life-event/detail.vue 从 localStorage 假收藏切换为真实 API + localStorage 缓存防闪烁
- 前端：ScriptLibraryView.vue 从 localFavorites 切换为 checkFavoriteScript 真实 API
- 前端：stores/app.js 新增 toggleEventFavorite / checkEventFavorite 方法
- 修复：审核发现的 UNIQUE 约束缺失、未使用 watch 导入、Controller 参数注解遗漏、Controller 委托 Service 构造 Response
