feat: 执行结果结构化-每条SQL记录status/affected_rows/duration_ms + 去掉工单详情优先级字段

后端:
- 新增 SqlExecItem/SqlExecResult 结构体
- MySQL/Redis/gh-ost 三条执行路径全部改为 JSON 结构化结果
- 每条 SQL 记录完整语句、状态、影响行数、耗时(ms)、错误信息
- 总耗时/开始结束时间一并记录

前端:
- ExecuteResult 接口匹配后端 SqlExecResult
- 表格展示每条 SQL 执行结果(序号/SQL/状态/影响行数/耗时/错误)
- 汇总卡片: 状态/总耗时/SQL数量
- 去掉工单详情中的优先级和变更原因字段
- 保留 plain text fallback 兼容旧数据

E2E验证: INSERT+UPDATE+ALTER 三语句全部成功, 结构化结果正确
