feat: TicketCreatePage tab化 + SchemaSidebar + Redis快速搜索 + Dashboard导航修复

TicketCreatePage 重构:
- SQL编辑器右侧新增数据库浏览器面板(tab化)
- 表结构Tab: 表列表→字段展开(PK/索引标记)→点击插入SQL
- 索引Tab: 选中表的索引详情(索引名/类型/字段/基数)
- Redis Keys Tab: DB选择器+Key模式搜索+Key列表+类型/TTL/值查看

SchemaSidebar 新组件(365行):
- MySQL/PostgreSQL: 左侧数据库表树→字段→点击插入SQL
- Redis: Key树(DB选择→模式搜索→Key值查看, 类似Another Redis Desktop Manager)
- 用于 QueriesPage 查询页面

Dashboard:
- 快捷按钮改用 useNavigate + onClick 替代 <a href>

API增强:
- redis.ts: 新增 getKeys/createKey/deleteKey 方法
- instanceDetail.ts: 导出 TableMeta/TableDetail/ColumnInfo/IndexInfo 类型接口
