fix(iis-migration): maljarka.tandemmebel.ru 502-on-HTTPS resolved

Root cause (NOT a migration defect): MoreThenCms tenant `maljarka`
had `dbo.Sites.SettingsData = NULL` (no `httpSecure` block) -> on a
real HTTPS request SnollaMiddleware throws KeyNotFoundException ->
502. HTTP served 200 fine. DNS/TLS/IIS binding all correct.

Fix applied to shared MSSQL (mssql.kzntsv.site): UPDATE Sites set
SettingsData with httpSecure{enableHttps:true,...} + recycle snolla
pool. Verified 443->200 server-local and external via 80.64.31.36;
kupimknigi untouched. Audit: maljarka was the only NULL-settings
site with a :443 binding (of 25); rimiz degraded for another reason.

- new concept: morethencms-null-settingsdata-https-502
- entities/ruvds-iis-host: maljarka moved from Degraded -> fixed
- index.md + log.md + STATUS.md + NEXT_SESSION.md updated
