✨ feat(frontend/backend): 批量操作与表格编辑增强并完善事务支持

- 批量导出/备份：表与数据库支持全选/反选/智能上下文
  - 右键菜单：单元格菜单支持设置 NULL
  - 编辑优化：大字段弹窗、仅值变化标记、提交只发送差异字段
  - 事务支持：PostgreSQL/SQLite/Oracle/DaMeng/KingBase ApplyChanges
  - MySQL 修复：提交前归一化 datetime，避免写入失败
  - 性能优化：移除 activeCell 重渲染、useRef 存储选中节点、防重加载
  - Redis 优化：二进制智能解码与视图模式切换
  - 资源更新：替换前端 favicon/logo
