feat(03-05): implement DeploymentStep and StepIndicator
- DeploymentStep: includeInstall toggle, configPath radio, scriptTargets checkboxes
- DeploymentStep: dispatches SET_DEPLOYMENT live on every control change
- DeploymentStep: Back button (SET_STEP(1)), Next/Review button (SET_STEP(3))
- StepIndicator: 3-step breadcrumb with checkmarks on completed steps
- StepIndicator: clicking step 0 dispatches SET_REMOTE_PARAMS({}) then SET_STEP(0)
- StepIndicator: never dispatches RESET — deployment options preserved
- All 5 WIZD-03 tests GREEN
