fix: wire triage recovery into SelfHealingManager and fix duplicate imports

- Pass recoverApprovedTriageTask and getSpecifyingTaskIds callbacks from
  TriageProcessor to SelfHealingManager in InProcessRuntime. Without these,
  approved triage tasks stuck in 'specifying' status were never recovered.
- Remove duplicate imports in ModelOnboardingModal.tsx that caused TypeScript
  errors (duplicate identifiers: useEffect, useRef, ToastType, fetchAuthStatus).
- Add mock for model-onboarding-state in App.test.tsx.
