WHAT is this pull request doing?

• Adds the type field to all bulk operation GraphQL queries and mutations
• Updates the generated TypeScript types to include the new BulkOperationType enum
• Improves the bulk operation status formatting to differentiate between query and mutation operations

How to test your changes?

1. Run a bulk operation query and verify that the type field is returned
2. Run a bulk operation mutation and verify that the type field is returned
3. Check that the status messages correctly show "objects read" for queries and "objects written" for mutations
