- New admin endpoints: GET /api/admin-backup/export streams the entire
data directory as tar.gz (after flushing queued writes); POST
/api/admin-backup/import validates the archive, snapshots current
data, replaces the folder, and reloads all in-memory state.
- Admin UI: "Full Data Backup" section with download and restore-from-
file controls in the Analytics panel.
- Fix admin TOTP secret path to honor SITEFORGE_DATA_DIR (moved base
path resolution to server/paths.js to avoid a circular import), so
2FA for admin and study users survives backup/restore.
