feat: update rommie model, reassign service ports, and fix deploy health check

- Upgrade rommie model from Qwen3-VL-30B-A3B to Qwen3.5-35B-A3B-UD-Q4_K_XL
  and update model URL port to 22079
- Reassign freecad_mcp_port (22032 -> 22063) and kernos_port
  (20201 -> 22062) for consistent port numbering
- Flush handlers before health check to ensure systemd reload
  completes before verifying the endpoint
- Update expected MCP health check status code from 405 to 406
