ipx-web: pass the tunnel's Access headers when it arrives as ::ffff: (#209)

Browse Source 
Caddy listens dual-stack, so the ipx_default gateway connects as ::ffff:192.168.64.1, and
remote_ip 192.168.64.1 does not match it: every Cf-Access-* header was stripped, the
tunnel's too. The browser suite binds Caddy to 127.0.0.1, IPv4 only, so it never saw it.

- Signing in through Cloudflare Access works behind ipx-web: Caddy took the tunnel's address for someone else's and dropped its sign-in headers (#209).
