feat(nginx): add local authorisation rules

This prevents devices with a source IP address outside of the allowed IP
addresses from connecting to the target location. This is useful for
internal-only locations, in case people make an attempt to directly
connect by modifying their `/etc/hosts` file or custom DNS to bypass the
lack of internal domains on public DNS.
