When backend_tls=true, the h2 transport was verifying the backend's
TLS certificate. This fails when the backend address is an IP (no
IP SANs) or uses a self-signed cert. Backend connections are to
trusted internal services — skip verification. Also change rift
metrics port to 9091 to avoid conflict with exod on 9090.

Rift-specific config routes metacrypt.svc.mcp.metacircular.net across
three listeners: L7 TLS-terminating to metacrypt-web on :443, L4
passthrough to API on :8443, and L4 passthrough to gRPC on :9443.
Docker compose uses host networking for direct port binding. Includes
self-signed cert generation script for initial L7 deployment. Updates
example config with metrics section and Unix socket for gRPC admin.
