audit: final sweep for hardcoded strings in components

Searched all components for hardcoded factual claims. Found:
- BootSequence.tsx: all content verified (done in 2.10)
- EducationSubsection.tsx: hardcoded education data duplicates data layer
  but all content verified against CV
- LastConsultationCard.tsx: NHS Band "8a" not in references, flagged
- ChatWidget.tsx: suggested questions are UI prompts, not claims
All findings logged in unverified-content.md.
