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.

docs/self-hosting/README.md is the complete operator contract: install
from the two reference files, first-run wizard walkthrough, update
procedure with the one-release downgrade window, backup/restore with the
sidecar, readyz-based troubleshooting (incl. the classic proxy/WebSocket
and APP_BASE_URL/CSRF mistakes), and a build-from-source note; linked
from the repository README; English-only by documented decision. The
reference compose gains a `caddy` profile (new Caddyfile) that publishes
80/443 and terminates TLS via Let's Encrypt for $DOMAIN — localhost uses
Caddy's internal CA for smoke tests. deploy/self-hosting-verify.sh
scripts the clean-machine test: a fresh directory with only the
published files boots to the wizard answering over TLS, then removes
itself; verified green on the stage host.

Imprint and privacy policy are two new Markdown instance settings
(legal.imprint, legal.privacyPolicy), edited by Site Admins in a new
"Legal pages" admin section with a toggleable rendered preview. The
preview uses the same shared pipeline the server renders with
(markdown → schema doc → escaped HTML), so stored markup can never
smuggle script to visitors.

The pages render publicly at /legal/imprint and /legal/privacy — as an
SPA route plus, like #56, a self-contained server-rendered HTML
document under /api/v1/legal/:kind. The endpoints are setup-exempt:
legal information stays reachable even while the first-run wizard is
pending. Unconfigured pages show a localized notice instead of 404ing,
and Site Admins additionally get a warning banner linking to the
settings. A new footer with both links appears on every SPA view
(editor, auth screens, public pages) and in the server-rendered
documents, whose shared shell moved to public/html-shell.ts and now
renders its chrome in the instance default locale (ADR 0012).

docs/self-hosting/legal-template.md ships imprint and privacy-policy
templates in English and German whose sections mirror Dorfteich's
actual processing activities (accounts, sessions, rate-limit IPs,
proxy logs, transactional mail, content, export, deletion, no
third-party requests), with a review checklist tied to security.md
§Privacy.

New `legal` i18n namespace (de+en); api and web e2e coverage including
a new CI legal pack (footer navigation, notice vs. admin banner, and
the admin form publishing a text end to end).
