feat: add docker-compose example for remote (ui.com cloud) mode

Adds docker-compose-remote.yml and matching env example for running
unifi-poller against the UniFi cloud API instead of a local controller.
Uses UP_UNIFI_REMOTE and UP_UNIFI_REMOTE_API_KEY for auto-discovery of
all Network-capable consoles via api.ui.com.
