[Bug Fix] Allow non-localhost hosts in docs development env

Rails 8's Host Authorization middleware blocks any Host header outside
localhost/private IPs by default, so accessing the docs dev server
through a VM hostname or Tailscale domain (e.g. devmachine.cloud) gets
rejected with "Blocked hosts". Clear config.hosts in development since
this is a non-public dev-only environment.
