Subject: [PATCH] fix(billing): gofmt channel.go and drop the redundant
 response-model hint
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- channel.go: 常量块里插入注释后 gofmt 会把 BillingModelSourceResponse 单独成组，
  原写法沿用了上一组的对齐空格，CI 的 gofmt 检查因此失败
  (internal/service/channel.go:45: File is not properly formatted)。
- 撤掉渠道表单里新加的那条提示：说明本就多余，且"只降不升"只在"相对基线收费"
  这个口径下成立，容易被读成"上游返回更贵的模型也不会多收"，反而误导。
