[Bug]: iconURL cannot be loaded from npmmirror

[zjjxwhh]

What happened?

When I specify the iconURL in librechat.yaml as a CDN link from npmmirror, the icon fails to display, and the browser's developer tools indicate net::ERR_BLOCKED_BY_ORB. However, when I specify it as a CDN link from UNPKG, the icon displays correctly. If I directly access the CDN links from npmmirror and UNPKG in the browser, the icons can both be displayed normally.

Steps to Reproduce

Configure the iconURL for endpoints in librechat.yaml as a CDN link from npmmirror

endpoints:
  custom:
    - name: "DeepSeek"
      apiKey: "${OPENAI_API_KEY}"
      baseURL: "${OPENAI_REVERSE_PROXY}"
      iconURL: "https://registry.npmmirror.com/@lobehub/icons-static-svg/latest/files/icons/deepseek-color.svg"
      # iconURL: "https://unpkg.com/@lobehub/icons-static-svg@latest/icons/deepseek-color.svg"
      models:
        default: ["deepseek-free-api"]
        fetch: false
      titleConvo: true
      titleMethod: "completion"
      titleModel: "gpt-4o-mini"
      summarize: false
      summaryModel: "gpt-4o-mini"
      forcePrompt: false
      modelDisplayLabel: "DeepSeek"
      dropParams:
        - "stop"
        - "user"
        - "presence_penalty"
        - "frequency_penalty"

I provided two iconURLs for testing. The first one, the npmmirror link, fails to display properly, while the second one, the commented-out UNPKG link, displays correctly.

I conducted some tests and asked the npmmirror development team. They informed me that to prevent illegal abuse of their CDN services, if the Referer in the request headers contains the .top top-level domain, it will return a 403 error. Unfortunately, the domain I am using is a .top top-level domain (I am just an ordinary user😢
