fix: remove /v1 prefix from agent API endpoints and resolve variable naming conflicts

- Update all agent command endpoints to remove /v1 prefix for API consistency
- Rename `success` variable to `is_success` in chain.py to avoid conflict with success() function
- Rename `output` parameter to `output_file` in genesis.py for clarity
- Add admin command help tests to verify command structure
- Update blockchain status endpoint from /status to /v1/health in tests
- Mark admin help command as working
