First half of the GUI-only backup roundtrip. Adds a self-describing
".picpeak" archive that can be downloaded from one instance and (later)
re-uploaded to another via the web UI only.
- picpeakExportService.createPicpeak(): dumps every table as NDJSON
(tables introspected at runtime — no hardcoded list, won't rot), plus
a manifest (format version, app version, DB engine, latest migration,
per-table row counts + checksums, includePhotos, contains_secrets),
plus files/ (business-docs + uploads always; original gallery photos
only when includePhotos). NDJSON is engine-neutral so the target
rebuilds schema via migrations then loads rows — enabling pg↔pg /
sqlite↔sqlite and forward-only auto-migrate.
- GET /admin/backup/picpeak/export?includePhotos= streams the file and
sets X-Picpeak-Contains-Secrets (the file holds plaintext SMTP pass,
admin hashes, API keys — the UI must warn).
- Purely additive: no existing backup/restore path is touched.
Integration test proves the archive shape, knex-table exclusion, and
row-count/NDJSON consistency (85 tables on the seed schema).
