fix: update API endpoints to use /api/v1 prefix, fix blockchain node URL, resolve variable scoping issues, and accept multiple success status codes

- Change marketplace endpoints from /v1/* to /api/v1/* for consistency
- Update blockchain status node 1 URL from localhost:8082 to localhost:8003
- Fix blockchain health endpoint to use /health instead of /v1/health
- Generate unique workflow_id using uuid.uuid4() instead of undefined agent_id variable
- Accept both 200 and 202 status codes for agent
