feat(iis-migration): win-acme HTTP-01 auto-renewal on RUVDS IIS

Stood up a permanent self-renewing Let's Encrypt pipeline on the RUVDS
IIS host, replacing the manual traefik acme.json -> PFX import and
closing the 2026-07-22 cert-expiry deadline (new 25-SAN cert valid to
2026-09-03, SYSTEM scheduled task renews 55 days before expiry).

Key obstacle: the MoreThenCms OWIN catch-all (owin:HandleAllRequests)
swallowed /.well-known/acme-challenge/. Solved by carving the challenge
path into a separate IIS application in a No-Managed-Code app pool, plus
patching win-acme's Web_Config.xml template to remove the inherited Owin
handler. Staging + prod validation green for all 25 hostnames; live TLS
smoke confirms the new cert is served (incl degraded maljarka/rimiz).

+## [2026-06-05] ingest | concepts/winacme-iis-owin-catchall-http01 — постоянный self-renewing LE pipeline на RUVDS IIS (win-acme v2.2.9, 25-SAN cert, SYSTEM scheduled task). Главное: OWIN-catch-all CMS жрёт `/.well-known/acme-challenge/` → решено отдельным IIS-приложением в пуле «No Managed Code» + патч шаблона `Web_Config.xml` (snять Owin-handler). Заменяет ручной [[traefik-acme-json-to-iis-cert-import]] для renewal'а; снимает зависимость RUVDS от домашнего traefik. Закрывает дедлайн cert-expiry 2026-07-22 (новый cert до 2026-09-03).

 ## [2026-05-28] ingest | concepts/es-destructive-delete-incident-2026-05-26 — RCA для удаления 3 user-индексов на canonical ES `elasticsearch.kzntsv.site` (books VDS stack 33) во время cutover-prep. Caller identity unrecoverable (audit log = X-Pack платный, traefik accessLog был выключен). 2 preventive controls applied + verified: ES env `action.destructive_requires_name=true` + traefik JSON accessLog. Источник: `.tasks/restore-elasticsearch-indices-books-vds.md` § Closure note.
