Clearly mark zone key roll automation steps as information and not actions for the user

[mozzieongit]

zone status --detailed shows which key roll steps (keyset commands) will be run next. Currently it is easily miss-interpreted as actions the user is supposed to take. It should be made clear that it is what the system will do next.

For example: #183 (comment)

Proposal:

Automatic key roll state (Cascade internal -- Operator: do *NOT* run this manually):
    Roll AlgorithmRoll, state Propagation1:
        Cascade will wait until the new DNSKEY RRset has propagated to all nameservers.
        Cascade will try again after 2025-10-09T12:16:46Z

I hope this screenshot with arrows clarifies why I thought the operator (i.e. "moi") had to run things. :)
