List watched domains and their health

The domains this project watches (watch_domain), each with status ok, warning or problem, the reason in one sentence, the findings (dangling DNS that points to a host where the domain is not set up, spam on the homepage, a changed title or host, expiry in 30 or 7 days, the certificate, and mail advice), whether ownership is proven, and whether the domain is parked. Checked once a day; the owner gets one mail per domain per day at most, for a new problem. Watching is included in the plan, up to limit domains. dns_cleanup lists, for every domain of the project on Hypamoon's nameservers (watched or not), how many records the previous host left behind: safe_to_remove and ask; GET /domains/{id}/dns-cleanup has the details.
