What this PR does / why we need it:

AI Foundation 的 provider HTTP 客户端使用 Spring 默认的 256 KB 内存缓冲上限。图片生成接口内联 base64 图片时(例如 gpt-image-* 总是返回 b64_json,单张图片可达数 MB)会超出该上限,导致请求以 DataBufferLimitException 失败。

本 PR 为 AiProvider 增加可选的 spec.maxInMemorySize(字节):

  • ProviderHttpClientFactory.webClientBuilder 应用 Provider 配置的值,未配置时保持 256 KB 默认(现有行为不变)
  • Console 校验限定取值范围为 1024–1073741824 字节
  • console/ai-foundation/providers 的供应商表单新增「响应缓冲上限(字节)」输入框

Does this PR introduce a user-facing change?

供应商支持按 Provider 配置响应缓冲上限(spec.maxInMemorySize),解决 base64 图片生成响应超出默认缓冲上限导致的失败。
