Proxy grab only

[MrKaon]

Is your feature request related to a problem? Please describe.
This is specifically related to ensuring that the IP used for both the search and the grab matches.

Describe the solution you'd like
If the search is performed by a third‑party service (NZBHydra via redirect, or Prowlarr) and the grab is handled by NzbDav, an IP mismatch can occur. We can configure a proxy in the indexers and also in NzbDav to solve this, but the stream also needs to pass through a proxy to reach the Stremio user.

If NzbDav included an option to apply a proxy only for grabbing, this issue could be resolved. The IP used for search and grab would match, while NzbDav’s other connections could continue without using a proxy.

Apparently, NzbDav already honours Proxy settings for containers: https://docs.docker.com/engine/cli/proxy/, including NO_PROXY, so I guess the remaining work could be the UI.

Thanks
