Allow additional trusted hosts during callback redirect

[axieum]

During development, our Django backend runs at http://localhost:8000/ while the frontend is at http://localhost:5173/.

The following host verification code restricts the redirect to the current request's host.

Could it be possible to merge in Django's ALLOWED_HOSTS setting so we can redirect them back to the original client that may be at a different host?
