Frontend half of the diagnostic shipped in 4812fcd. Adds:
- BackupIntegrityCard component — runs the check on demand, surfaces
the five summary counters (total / verifiedOk / existsButNoHash /
missing / hashMismatches), and expands collapsible result tables
for missing files + hash mismatches. existsButNoHash is exposed as
a separate amber-toned bucket so admins can distinguish hash-
verified evidence from existence-only at a glance — the latter is
explicitly weaker in a legal dispute and the UI says so.
- "Integrity" tab on BackupManagement, alongside the existing
Dashboard / Configuration / History / Restore tabs. Card is
portable — when the System Health page (backlog item) lands it
can lift the component without changes.
- Post-restore CTA on the RestoreWizard success card (D2 follow-
through): "Verify document integrity now" button that switches
the parent tab to Integrity. The audit trail captured at sign /
issue time is worth nothing if the documents it refers to are
missing from the restored copy — verifier surfaces that drift
in one click before the admin trusts the restored state.
i18n strings added in EN + DE (per user_languages — only those two
are native; other locales fall back to the English defaults and
should be flagged for native-speaker review per
feedback_translation_flagging if anyone picks them up).
