[Feature Request] Separate application display language settings and accept-language content of request header

[MNDIA]

The status quo is :
that the application display language is bound to the request header language, and the request header language will always contain information about languages other than english. It's out of control.

What daily use is affected:
Some sites judge the accept-language content of request headers and redirect to other servers due to the presence of a specific language

Changes required:

1. Separate application display language settings and accept-language content of request header. Both can be individually set manually in the settings (Major requirements)
2. Like UA settings, different request headers are used for different website presets. There are global request headers, and 网站设定 request headers for each site.
   The request header override feature includes at least the ability to customize the accept-language attribute
