offers.export/orders.export/invoices.export gated nothing on the backend (PDF
routes enforce *.view); they only toggled frontend buttons and showed dead
role checkboxes. Migration deletes them (+ role grants) and idempotently seeds
the 12 enforced doc perms (offers/orders/invoices x view/create/edit/delete) +
admin grant, so a fresh prod DB has them (closes the seed-only drift gap).
Route reverts to orders.view; the 8 frontend *.export checks now use *.view.
