* Automatic authentication for backend on Github Codespaces
When running reflex on Github codespaces, the port forwarding mechanism
requires authentication, which happens automatically when first accessing the
port via HTTPS; however since the backend connects over the WSS protocol
instead, it gets an access error with no way to redirect to Github's
authentication servers to get the port open.
This PR adds an automatic redirection mechanism to a backend route when there
is a connection error accessing the frontend. After the backend route loads, it
redirects back to the frontend, but now it can connect to the backend via
websocket because the port forward is authenticated.
