A job that has a wizard now asks "Guide me / I'll do it myself" each time
it starts; nothing is remembered. The shared wizard shell gives every guide
a stepper, a side panel on what each step does and how to undo it, and the
way forward or back.
Automatic DNS, from a domain's DNS section:
- finds where the domain's DNS is hosted from its SOA and NS records, and
offers that host when the server can drive it;
- for the major hosts, steps to create the narrowest credential, and the
field named as the steps name it;
- records grouped by what they do, TLSA off unless the zone is signed;
- saves the provider and switches the domain over, removing the provider
again if the switch fails;
- watches the publishing task and public DNS, ticking each record green,
and boils a host's refusal down to its distinct messages;
- for hosts it can't drive, or domains not in DNS yet, every record laid
out for copying, with the same live checks.
