refactor: ♻️ 基于 gorm 钩子实现自动缓存失效机制，再也不用牵一发而动全身写删缓存逻辑了~ - 通过 gorm hook 监听 MySQL 数据变更 🧩 - 自动删除对应表相关缓存，实现缓存失效自动化 🔄 - 移除原本写在 sv 层的手动删缓存逻辑 🧹 - 解耦业务逻辑与缓存控制，结构更加清晰 ✅ fix: 🐛 修复将任务类加入日程接口的时间字段遗漏问题 - 由于前版本 MySQL 表结构更新 - 漏写插入起始时间字段逻辑，导致500报错，现已补充 ⏱️ fix: 🐛 修复获取最近已完成任务列表接口的多个问题 - 移除不应存在的幂等键 🔁 - 修复“一个event输出多次”的问题（原因出自 dto 转换函数） 🔧 undo: ⚠️ 删除任务类接口未处理已安排任务块的解除逻辑 - 当前删除任务类时，未解除已被安排的任务块 - 该逻辑存在缺陷，计划在后续版本内修复 🛠️
