Add full-state .zip backup (export + import) in Einstellungen 68cf7114fb

Adds a round-trippable backup of the entire app data directory to
a single .zip file, exposed in the existing 'Import / Export'
section of the Einstellungen page.

Backup layout (inside the .zip):
- manifest.json     format version, app identifier, UTC timestamp
- data/             every JSON key from the JsonStore
- antraege/         Antrag attachment directories
- vorlagen/         user-added ODT templates

Import replaces the three subdirectories in-place — anything not
present in the archive is deleted — so the user-visible state is
fully recreated. A destructive red confirm dialog gates the
import, and the success snackbar reminds the user to restart
the app.

Safety:
- formatVersion check on import so future schema changes can
  refuse old backups cleanly (with no data loss, since the
  delete-then-write only happens after the manifest validates).
- Path-traversal check: a resolved output path must live inside
  the intended subdirectory (data/, antraege/, vorlagen/);
  anything that escapes is rejected with a BackupException.
- Files with a top-level segment outside the three allowed
  directories are silently ignored.

Platform: export/import require a real filesystem, so the two
buttons display an unsupported-platform snackbar on web/Android/
iOS (the existing CSV export uses the same guard).

Tests (8 new): export counts, full roundtrip preserves data and
deletes leftovers, missing-file error, missing-manifest error,
wrong-format-version error, files outside allowed dirs ignored,
path-traversal inside allowed dirs rejected.
