fix(server+ci): 修 go-integration 真 bug + e2e 免疫代理(CI 收尾)

DinD 修复后暴露的两个 CI job,诊断:

Go integration(真 test-drift bug,早前会话改动遗留):
- auth/integration_test:Register/Login 补 ip + DeviceMeta 参数(sessions/
  device-meta 改动后陈旧调用,构建失败)。
- usage/usage_integration_test:手写测试 schema 补 ad_bonus_minutes 列
  (migration 000020 加的);重写 TestIntAdsUnlockAccumulates 断言对齐 ad-unlock
  转累加式(UnlockAd→AddAdBonusMinutes,不再 stamp ad_unlocked_at)。
- devices/devices_integration_test:套餐种子 pro=5→3(migration 000019 改的)。
- devices/context.go(生产 1 行):CtxKeyUserID 别名到 codes.CtxKeyUserID——原为
  独立 devices.ctxKey 类型,与 auth 注入的 codes.ctxKey 类型不同→context 取键
  失配(休眠 bug,中间件目前仅测试接线)。go build 通过。

E2E(环境问题,非脚本):删 ci.yml 里多余的 apt-get(openssl/curl/python3 已在
golang:1.25 镜像内;原 apt 走 Docker Desktop 代理→本机死口,徒增脆性)。脚本
本身本机直跑通过。

验证:go test -tags integration -count=1 -p 1 ./... 全 ok;go build ./... clean。
