feat(claim): 人工履约单领取页只显示「人工处理中，请等待客服」

未命中 AFFILIATE_DASH_SKU_MAPPING 的抖音单显式回落 manual_dispatch（人工），这类单没有
自动发货通道（无 claim token、无绑定二维码），但卡券 cert_link 仍指向 /h5/<订单号> 领取页；
原页面会让买家「输 UID」，提交后没有任何自动发货动作，属于误导买家。

- 后端 kuaishou-cloud-claim-context.ts：新增 MANUAL_FULFILLMENT_MESSAGE 与
  resolveManualFulfillmentMessage(executorKey)（manual_dispatch → 等待话术，其它执行器空串）；
  三个 payload builder 统一输出 manualFulfillment / manualFulfillmentMessage
- 前端 claim-snapshot.ts：输出 isManualFulfillment / manualFulfillmentMessage，
  progressText 同步显示等待话术
- 前端 ClaimPage.tsx：在「渠道已下线」之后、「输 UID」之前插入人工单卡片（只读 + 刷新状态），
  人工单不会自动轮询（无 expectedUid → 不安排下一次轮询）
- types/claim.ts：补齐两个可选字段；话术只在后端维护一份，前端只做兜底

验证：后端 npm run check（701 单测）与前端 npm run check（格式/lint/类型/143 单测/构建）全绿
