Address PR review comments

- Flatten directory structure: remove barrel file, move files up to /jobs
- Remove .passthrough() from zPreviewOutput, zPaginationInfo, zJobsListResponse
- Align nullable/optional with OpenAPI spec (outputs_count now nullable)
- Remove big comment block sections
- Change extractWorkflow return type to unknown
- Move zWorkflowContainer schema to jobTypes.ts
- Add interface types to test helper functions
- Add fetchHistory offset test for priority calculation
