reverse_proxy is the first built+applied service role; add the per-service
records CLAUDE.md/ADR-002/008/017/021 require. Add access__*/backup__* data to
defaults as the source of truth (ADR-021/022). reverse_proxy is stateless (ACME
certs re-issue via HTTP-01), so it declares backup__state: false with a reason
rather than a BACKUP.md (ADR-022 convention).
The access__*/backup__* cross-role field names intentionally don't carry the
reverse_proxy__ prefix, so each is marked `# noqa: var-naming[no-role-prefix]`
(ansible-lint has no per-prefix allowlist; rule stays enabled elsewhere).
