refactor(server): 消除与 Core 的重复类型定义

- 删除 Server 中 60+ 个与 Core 重复的类型定义
- 将动态导入 (await import) 改为静态类型导入 (import type)
- 保留必要的运行时静态导入
- 修复测试文件中的 mock 初始化问题
- 净删除约 960 行重复代码

重构文件:
- routes/checkpoints.ts: 删除 155 行重复类型
- routes/agents.ts: 删除 93 行重复类型
- routes/commands.ts: 删除 83 行重复类型
- routes/mcp.ts: 修复类型窄化
- routes/hooks.ts: 已使用静态导入
- routes/providers.ts: 删除 63 行重复类型
- session/manager.ts: 删除 41 行重复类型
- routes/sessions.ts: 添加类型导入
- permission/handler.ts: 添加类型导入
