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).
