✨ feat(redis): 新增Redis数据源完整支持

- 后端实现：新增Redis客户端接口与go-redis实现，支持SSH隧道连接
  - API方法：新增21个Redis操作API（连接/Key/Value/命令执行等）
  - 连接配置：ConnectionModal支持Redis类型，自动识别端口与认证方式
  - 数据浏览：RedisViewer组件支持Key列表展示、类型识别与分页加载
  - 值编辑器：支持String/Hash/List/Set/ZSet五种数据类型的查看与编辑
  - 二进制处理：自动检测二进制数据并以十六进制格式展示
  - 命令终端：RedisCommandEditor支持多行命令执行与结果展示
  - 交互优化：JSON语法高亮编辑、一键复制值、面板宽度可调整
