🔒 feat: Authenticated Image Requests

[danny-avila]

Summary

Implemented authenticated image requests, ensuring secure access to image resources.

This is a bare minimum approach for validation. It is best to use Firebase (hopefully more providers in the future) and manage a CDN policy, but this at least prevents the local images from being "public."

It remains to be seen how this may affect remote environments, as the approach simply relies on browser cookies. A toggle in this case may be necessary.

Also, this may not give the impression that images are secure when they are cached by the browser. Clearing browser cache and trying to access an image outside the app will prove otherwise.

Closes #2385

Changes

• Added authentication middleware to verify user credentials for image requests.
