feat(concurrency): trace 一致性 hash 亲和 + 透传 stream 优化 (#20 )

配合 pricebot 单机多进程:透传层按 trace_id 把同一次比价/领券的所有帧
亲和到同一 pricebot 实例,使进程内内存维护 state、无需 Redis。本仓改动:

- 一致性 hash: 新增 app/core/pricebot_router.py(ketama 环,1000 虚拟节点)
  + pick_pricebot(trace_id),md5 纯函数、跨 worker 一致;实测负载偏差 4%、
  6→7 扩容只重映射 ~13%(取模会 ~85%)。
- 实例列表: app/core/config.py 加 PRICEBOT_INSTANCES(逗号分隔)+
  pricebot_instances property;留空 fallback 单实例,向后兼容。
- 透传亲和 + stream: api/v1/compare.py + coupon.py 改为读原始字节、只
  loads 一次拿 trace_id 选实例、转发原始 bytes 不重序列化(省 ~半透传 CPU,
  单 worker 即可扛高并发,避开多 worker 破坏短信内存表的坑);覆盖
  intent/recognize、intent/step、price/step、coupon/step 四端点。
- .env.example 加 PRICEBOT_INSTANCES + PRICEBOT_COMPARE_TIMEOUT_SEC。

feat: coupon/step 透传去鉴权(MVP) + 技术债账本补充领券落地遗留

- /api/v1/coupon/step 去掉 CurrentUser 鉴权:MVP 领券不鉴权,device_id 透传给
  pricebot 区分设备;user_id 绑定 + 用户级画像见账本 P1,待补
- docs/待办与技术债.md 补「阶段1领券落地遗留」:FloatingButton 死代码、ComparingScreen
  弃用、ApiClient unused 常量、权限引导最简版等待清理项

feat(coupon): add /api/v1/coupon/step proxy to pricebot

- new POST /api/v1/coupon/step, JWT-authenticated, async httpx forwards body to pricebot
- new PRICEBOT_BASE_URL / PRICEBOT_REQUEST_TIMEOUT_SEC settings (default localhost:8000)
- error handling: pricebot unreachable / 5xx -> 502 with friendly message
- tests: auth, passthrough, 5xx, unreachable, invalid json (5 cases, all pass)
