The original GET route used a correlated NOT EXISTS / FIND_IN_SET
subquery over the entire catalog_items table for every recent import
audit entry, causing server timeouts when the audit log or catalog
grew large. The per-item host-page validation inside the create
action also issued one SELECT + one UPDATE per moved offer.
Changes:
- GET /api/admin/import/organize: replace the correlated subquery
with a bounded candidate list and a JS-side placed-set check, then
resolve all needed base items in a single indexed SELECT. This
bounds the query cost regardless of catalog or audit log size.
- organizeImportFurni action: validate mover ids in one SELECT, then
batch every move per group into a single UPDATE with a CASE
expression instead of one UPDATE per item.
- OrganizeImportsDialog: add a 45-second abort timeout on the fetch
and a distinct load-error state so the UI never silently hangs.
- Add 'loadError' translation key (en + nl).
