[Feature] Let RR download files on its own and then send it to requester instead of a simple redirection

Is there an existing issue for this feature?

• Yes, I have searched the existing issues and it doesn't exist.

Feature Description

I would like to keep the minio server private, so only accessible internally through the docker network.
Reactive resume should then be able to download on its own whatever file saved on minio (in my case using the local network with STORAGE_URL=http://minio/reactive-resume) and upload it then to the requester instead of simply redirecting to the STORAGE_URL (which right now must be reachable from the browser)

But then, when you upload a picture on your resume, this has to be accessible via a public URL for the chrome browser on the server to load the image and place it onto the document, and it also has to be visible if the resume is made public so that anyone can visit a URL to view the resume (generating a signed link to access the image every time an anonymous user loads a resume would be too much load on the server).

the chrome browser on the server would still have access to the minio local server since it would have to be on the same network or reachable anyways
