fix(integrations): correct integrationType key so the integrations page renders

The merged email-verification blocks (zerobounce, neverbounce, millionverifier)
were serialized into integrations.json with a typo'd `integrationTypes: ["sales"]`
plural array instead of the singular `integrationType` the catalog reads. They
fell into an `undefined` category bucket, and sorting sections by label threw
"Cannot read properties of undefined (reading 'localeCompare')", erroring the
whole page.

- Correct the three entries to `integrationType: "sales"` (matches each block
  config's IntegrationType.Sales and the generator's output)
- Defensively skip any integration without an integrationType when grouping so a
  single malformed catalog entry can never crash the page again
