Fixing redirection issue for logged-in users (#26105)

This PR addresses an issue where logged-in users get redirected to the
homepage when trying to access a URL with the redirect_to parameter. The
issue was traced back to a middleware function in
services/auth/middleware.go that redirects logged-in users to the
homepage. This function didn't account the redirect_to parameter.

The fix modifies the middleware function to check for this case and
redirect the user to the specified URL instead of the homepage.

Closes: #26005
