Rework copy voice, add /review, Kanidm-gated applicant review

English URLs throughout; review.yaml adds a qualifies-gated question
listing applicants via the generic NATS-KV resource mechanism, with
Invite/Decline transitions. Content pass: concrete/positive phrasing
(no negation constructions), warmer inclusive tone, light puns in the
encouragement lines.
