✨ feat(redis/monitor/oracle/data-viewer): 新增 Redis 实例监控并优化 Oracle 大表预览体验

- 新增 RedisMonitor 面板，展示 QPS、内存、CPU、连接数和键数量趋势图
- 引入 recharts 依赖并补齐监控图表所需前端包与锁文件
- Sidebar 新增 Redis 实例监控入口，TabManager 与 TabData 接入 redis-monitor 页签类型
- RedisCommandEditor 支持多行脚本块解析、选区执行、耗时记录与终端化结果展示
- Oracle 表预览移除自动精确 COUNT(*)，避免打开大表时额外阻塞
- 无筛选整表预览接入 ALL_TABLES.NUM_ROWS 近似总数展示，并拆分近似总数与近似总页数语义
