Receiving half of the roundtrip. picpeakImportService.importFromPicpeak():
- Validates the manifest: rejects non-picpeak files, a newer format, an
engine mismatch (pg↔pg / sqlite↔sqlite only), and a backup from a NEWER
schema than this instance (forward-only). knex_migrations absence is
tolerated (test harnesses).
- Snapshots the current logged-in admin, then wipes + reloads every table
from the backup NDJSON in one transaction with FK enforcement suspended
(pg: session_replication_role=replica reset before commit; sqlite:
defer_foreign_keys). knex_migrations is never touched, so the target's
schema/migration state is preserved.
- Re-injects the current account so the operator is never locked out; a
backup admin colliding on email is overwritten with the current creds.
- Restores files/ into storage and detects external-media references so the
caller can prompt to reconfigure the mount.
Roundtrip integration test proves: backup data restored, current account
survives a full override (different email → added), and the email-collision
case keeps the operator's password.
