      feat(gateway): raise upstream response read limit 8MB -> 128MB (configurable) · bf0bbe0b
      erio authored 
      图片生成 API 返回的 base64 内联图响应经常超过 8MB 单次读取上限，被
ReadUpstreamResponseBody 拦截成 502 upstream_error。

单张 4K PNG base64 最坏约 67MB，多张候选图或 imageSize=4K 的 image_generation
一次请求能轻松到 30MB+。把默认上限提到 128MB 能覆盖 2-3 张 4K 图，相对
请求体上限 256MB 仍有缓冲；同时抽出 config.DefaultUpstreamResponseReadMaxBytes
共享常量，viper 默认值和 service 层兜底共用，消除两处同步魔法数字。

仍可通过 gateway.upstream_response_read_max_bytes 配置项覆盖。

      refactor: extract ReadUpstreamResponseBody to deduplicate upstream response read + too-large error handling

Consolidates 9 call sites of resolveUpstreamResponseReadLimit + readUpstreamResponseBodyLimited + ErrUpstreamResponseBodyTooLarge error handling into a single ReadUpstreamResponseBody function with TooLargeWriter callback for API-format-specific error responses (Anthropic, OpenAI, countTokens).
