test(05-00): add failing TECH-01 and TECH-02 test cases to ReviewStep.test.tsx

- Add WizardConsumerSetup helper to dispatch SET_DEPLOYMENT in tests
- Add renderWithDeployment helper for scriptTargets-specific rendering
- Add TECH-01-a: intune-only — Intune blocks present, RMM block absent (RED)
- Add TECH-01-b: rmm-only — RMM block present, Intune blocks absent (RED)
- Add TECH-01-c: neither target — only rclone.conf OutputBlock shown (RED)
- Add TECH-01-d: neither target ZIP — downloadZip with 1 file only (RED)
- Add TECH-02: Back button rendered and not disabled (RED)
