feat(admin-client): add manual experience creation in ExperiencePage

管理员现在可以在"系统经验管理"页面手动创建经验，而不仅限于审核系统自动生成的经验。

实现细节：
- experience.api.ts: 新增 CreateExperienceDto 类型和 createExperience() API 方法
  - 调用 POST /memory/experience 创建经验
  - 创建后自动调用 POST /memory/experience/:id/approve 激活
  - 管理员手动创建的经验无需额外审核流程
  - sourceConversationId 标记为 'admin-manual' 以区分来源
  - 默认置信度 80%（高于系统自动生成的 45%）
- useExperience.ts: 新增 useCreateExperience mutation hook
  - 创建成功后自动刷新经验列表和统计数据
- ExperiencePage.tsx: 新增"新建经验"按钮和创建表单弹窗
  - 表单字段：经验类型、适用场景、经验内容、相关移民类别（可选）、置信度
  - 移民类别下拉：QMAS/GEP/IANG/TTPS/CIES/TechTAS
  - 表单验证：类型、场景、内容为必填

这与方案A（评估门控失败自动沉淀经验）互补：
- 自动路径：Gate failure → PENDING experience → 管理员审核 → 激活
- 手动路径：管理员直接创建 → 自动激活（无需审核）
