refactor: 移除前端 Mock API，新增共享组件，优化认证流程

- 删除 mock_api_client、mock_calendar_service、mock_history_service - 新增 fixed_length_code_input、link_button、message_composer 共享组件 - 优化登录/注册/密码重置页面使用新组件 - 简化 injection.dart 移除 mock 分支 - 更新 env.dart 配置（BACKEND_URL 替换 API_URL） - 后端 agentscope 工具和测试更新 - 重构 AGENTS.md 文档结构 - 新增 deploy/ 目录和 protocol 文档

+Follow lightweight testing strategy - prioritize value over coverage:

- **MUST** add widget tests to reduce layout regression risk:
-  - Verify primary content stays centered relative to the usable viewport.
-  - Include at least one constrained scenario (e.g., small height **or** large text scale).

+- Service layer logic (business rules, API call handling)
