Adds docs/operations/update-runbook.md (obtain, verify by digest, back
up, apply, verify, roll back) with the migration behaviour stated
explicitly: a failed migration rolls back its own transaction but is
recorded in _prisma_migrations and blocks every further migrate deploy
(P3009) — including a re-deployed old image — until migrate resolve
--rolled-back; semantically irreversible migrations have exactly one way
back, the pre-update backup set. No rolling updates on a compose stage.
Rehearsed in the isolated environment of #220: regular update to a v2
image set, then a deliberate failed-update (P3018 division by zero,
schema change proven rolled back) with image-rollback-alone shown
insufficient and the documented recovery executed. Protocol:
docs/vs-nfd/98-update-rollback-protokoll.md. ADR 0024 decisions 5+6
recorded as executed; operations handbook and restore runbook updated;
plan checkbox P1-3 ticked.

Since #224 read_events is partitioned; the dump carries per-partition
primary keys as own entries, and pg_restore --clean emitted DROP
CONSTRAINT against inherited constraints, which PostgreSQL refuses. The
restore then reported FAILED although the content was restored. Dropping
and recreating the public schema first makes every --clean drop a no-op
and the restore faithful: objects created after the backup no longer
survive. Verified in the isolated environment of #220 (set
20260731-132200, exit 0, readyz green).

ONE consolidated every Docker stack under /srv/DOCKER (BASEL
convention, tracked in stwaidele/infrastructure-one); the three
Dorfteich stages follow. Deploy targets in cd.yml (test/int) and
prod-deploy.yml plus the docs now point at /srv/DOCKER/dorfteich-<stage>.
Data lives in named volumes keyed by the unchanged compose project
name, so the directory move carries no data migration. The go-live
checklist's uptime-kuma path already lives under /srv/DOCKER — the doc
just catches up.

Deliberately committed together with the host-side move: this commit
must not deploy before the directories exist at the new path.

5cef359b8f Nextcloud backup target: admin-configured, manual + scheduled uploads, in-app restore (#103)

Off-host backups for every self-hoster, configured entirely in the admin
UI — supersedes the host-specific mirror plan behind #84.

shared:
- webdav.ts (new package entry like token-crypto): minimal WebDAV client
  with basic auth — PROPFIND (tolerant multistatus parser), MKCOL, PUT
  (streamed), GET, DELETE; Nextcloud DAV path derived from the plain
  server URL, explicit DAV bases pass through
- backup-status.ts: additive remote-upload status in status.json, the
  restore-status.json contract (running/succeeded/failed + staleness
  bound), the backup_command/backup_maintenance NOTIFY channels, and the
  one-bundle-per-set naming (dorfteich-backup-<id>.tar.gz)
- backup-set.ts moved here from apps/backup (api lists local sets)

backup sidecar:
- reads the backup.* instance settings directly from the database (admin
  changes apply next run; local retention row overrides the env) and the
  app password from the secret store
- after each successful set: bundle dump + files archive + manifest into
  ONE self-contained tar.gz, upload via WebDAV per schedule
  (off/daily/weekly; manual runs always upload), prune remote bundles —
  never the newest — and record the outcome in status.json; upload
  failures alert via a new backupUploadFailed mail (de+en)
- command listener on backup_command (run / restore) with a serial queue
  against the nightly timer
- restore orchestrator: restore-status.json → maintenance NOTIFY →
  grace → (remote: download + manifest-verify bundle) → terminate other
  DB connections → shared perform-restore path (same code as restore.sh)
  → final status + maintenance exit

api:
- MaintenanceGuard (global, registered before the setup gate): 503
  maintenance_mode while restore-status says running; health endpoints
  and the new public GET /backup/restore-status stay exempt; a stale
  running state (crashed sidecar) unblocks after 30 min
- MaintenanceStateService watches the file and restarts the api after a
  successful restore (fresh caches, migrate-on-start for older dumps);
  main.ts refuses to touch the database while a restore runs — a
  container restarting mid-restore must not race pg_restore with
  migrate deploy
- worker sweeps (conversion, mail outbox, scheduler) catch transient
  database failures instead of dying on an unhandled rejection — the
  restore's connection termination crashed the api in verification
- backup admin endpoints under /admin/system/backup: settings (live
  connection test before save, password write-only into the secret
  store), nextcloud/test, sets (local via the ro backups mount + remote
  via WebDAV), run + restore (type-to-confirm backstop, source
  validation) — commands travel as NOTIFY payloads; audit actions
  backup.settings_changed/run_triggered/restore_requested
- readyz: new warning-level backup_remote check while a target is
  configured (26 h daily / 170 h weekly bound)

collab:
- maintenance listener: on enter, persist + close every live session and
  refuse new connections until exit (failsafe timeout 30 min) — no
  in-memory document may write pre-restore content back afterwards

web:
- Admin → System backup section: status card with remote facts and a
  "Back up now" button, the Nextcloud settings form with test button,
  and the restore picker (local + remote sets, type-to-confirm)
- global maintenance screen: any 503 maintenance_mode flips the SPA to a
  status page polling the exempt endpoint, reloading when the instance
  returns

Verified end-to-end against a live stack (fresh DB, native api + sidecar,
fake WebDAV server): configure → test → manual backup → bundle upload →
readyz/sets/status surfaces → remote restore with maintenance gate,
marker rollback and api restart; suites: shared 21, backup 9, collab 11,
api 58 files green, lint + i18n:check + typecheck clean.

6e99cb35fc Trigger the restore drill on demand via drill-* tags (#87)

Gitea 1.22 cannot dispatch workflows through the API or UI (that lands in
1.23), so pushing a drill-* tag is the on-demand path next to the monthly
schedule.

New scheduled workflow (monthly + on demand) runs deploy/backup/drill.sh:
it reads the drilled stage's backups volume strictly read-only, restores
the latest successful set into a throwaway Postgres and volumes under a
unique drill prefix via the backup image's restore path, boots the api
against the result, and verifies readyz (database + migrations), row
counts, rendered content in the page cache, a public API request, and a
media byte-check against the attachments table — then tears everything
down, also on failure. Each run reports its outcome as a comment on the
pinned "Restore drills" issue (#98). docs/operations/restore-runbook.md
carries the manual procedure, which doubles as the Prod relocation path;
pre-go-live the drill restores the Test set (switch the source volume at
go-live, #89 — off-host fetch from the BASEL mirror stays with #84).
