docs/vs-nfd/70-betriebshandbuch.md: installation as run on the real
stages (airgap variant explicitly pending #218-#221 with what already
exists as groundwork), update/rollback incl. the no-down-migrations
caveat, backup/restore with the ADR-0026 target allowlist and the
rehearsed monthly restore drill (evidence: logs on #98), the full
scheduler-job table (cadences verified against code), the deletion-and-
destruction chapter built on the #228 copy list (per content type:
what deletion reaches, what remains, immediate-destruction path,
decommissioning), and role separation incl. the deliberate limits of a
Site Admin and the honest note that Site Admin read-bypass makes the
content/platform split non-absolute app-side. Every procedure carries
its evidence level (erprobt / nicht geprobt / offen) — nothing claimed
above what was actually executed.
