proxy-manager: nginx proxy manager in officer

reads hosts and certificates against a live NPM 2.15.1. one grantable
permission, with /_config owner-only — reading which hosts are healthy
is worth sharing, an NPM admin login is not, and NPM has no read-only
role.

the quirk that shapes the whole plugin: NPM answers an unauthenticated
read with 404, not 401, because its router only registers a resource
once a token is present. so 'not signed in' and 'no such endpoint' are
the same response, and a naive client tells you a feature is missing
when your password is wrong. the client mints a fresh token and retries
once, then reports a persistent 404 as likelyAuth.

certificates sort by expiry rather than name, which is the only ordering
that answers a question.

no create/edit/delete and no cert issuance: NPM's own UI does those and
a wrong proxy host takes a domain off the internet.
