feat(matrix): PlcSps as a composite device target (SBOM/CVE/DAST/pentest)

A PLC/SPS device is two layers — the control application and the device it
runs on (firmware/OS + reachable runtime services). Previously PlcSps offered
only PlcControlLogic, so a CODESYS-on-Yocto device's firmware and network
attack surface was invisible.

- scan_matrix: PlcSps now offers FirmwareStatic + Sbom + Cve (require a firmware
  image) and Dast (require a running endpoint, e.g. WebVisu), and
  supports_pentest(PlcSps) is now true. Control-logic stays default-on; the
  device-level scans are offered but opt-in (default-off) — firmware-image
  SBOM/CVE execution is shared with the firmware families and still landing
  (#151/#128), so they must not silently auto-run.
- orchestrator: the PLC branch no longer early-returns, so a PLC device with a
  reachable endpoint also runs DAST (the wired path) after the control-logic scan.

Part of the CODESYS-on-Yocto coverage tracker (#167). Closes #164.
