post(case-studies): running production infrastructure solo — 162 containers, three hosts (EN+ZH) + og/banner

The Phase C1 keystone asset (Story B). Publishes the infra case study:
- architecture: 3 hosts / 162 containers / 78 compose stacks with the per-host split
- incident record: the monitoring panels that lied, and the Passbolt cascade
- how the numbers are re-derived (verify_infra.py) rather than remembered
- no uptime percentage: availability is not measured, so the post says 'monitored'
- hire CTA (case-study convention)

EN + ZH twins, og + banner generated and measured (OG 5 tags/1 row, banner 8 lines delta 2).
