fix(tests): mock scaffold destructure + collection-pool + pocketbase startup

- orders-service.test.ts: destructure capture-group bug on regex match
  (was assigning m[0] to 'field', so filter clauses never matched).
  Two pre-seed tests were masked by the bug.
- quotes-service.test.ts: createQuoteFromEmail now returns 0
  attachments; the n8n flow uploads them in a follow-up step. Update
  the assertion that still expected the old embedded-base64 count.
- collection-pool/page.test.tsx: tests assume ONE supplier group with
  multiple rows; supply that shape and scope the selectors. Also wait
  for data load in the chevron test and gather list items across all
  <ul> elements in the sort control helper.
- pocketbase.ts: wrap authStore.onChange registration defensively so
  the test mock (no authStore) doesn't throw at startup.
- stock-orders/page.tsx: drop the re-export of
  STOCK_PURCHASE_STATUS_VALUES on the page module — Next.js page
  route files only allow the default export.
- collection-confirm/view-model.test.ts: buildConfirmNote input is
  Pick<InvoiceDetails, 'date' | 'number'>; drop the extra setBy fields.
