An apex domain's own records are still saved with the hostnames'
records, under the domain's name, so the port and TLS checks find its
addresses. Notifications about them now start `Domain:`, decided by the
configured domains. The dashboard and /api/v1/status, which read only
the saved state, take a hostname entry whose name also has a domain
entry as that domain's own records: the dashboard shows them in a second
table under Domains, the API in the domain's `recordsByNameserver`, and
neither lists or counts them as hostnames. The startup notification
counts domains and hostnames from the configuration. README says which
of a domain's own records are watched and how their changes are
notified.
