docs(guide): add platform.production-checks + new DEVOPS section (backups, security)
- platform.production-checks: the daily prod health sweep (deep actuator/critical
set, Loki ERROR+5xx top-5, backup freshness, ClamAV per-VM) -> 06:30 email report.
- NEW DevOps nav section in the reader (SPECIAL + section block + expandFor).
- devops.backups: pg_dumpall->Swift nightly job, verify/restore, gaps (#13/#14/#15).
- devops.security: ClamAV/firewall posture from the 2026-07-02 sweep — FAILING,
remediation in #16 (Critical, PCI CDE) / #17. Reconciler: devops = concept docs.
