Replace fuzzy string matching with semantic AI matching to fix false
positives where similar-sounding but different companies were matched
(e.g., "Families First CiC" incorrectly matching "FAMILIES AGAINST
CONFORMITY LTD").
Changes:
- Add ICompanyNameMatcherService interface and AICompanyNameMatcherService
implementation using Claude Sonnet 4 for semantic company name comparison
- Add SemanticMatchResult and related models for AI match results
- Update CompanyVerifierService to use AI matching with fuzzy fallback
- Add detection for public sector employers, charities, and self-employed
entries that cannot be verified via Companies House
- Update tests to work with new AI matcher integration

When a company appears multiple times in employment history (e.g.,
multiple roles at same company), penalties are now applied only once
per unique company, not per employment entry.
- Unverified company: -10 pts once per company (not per role)
- Company flags (incorporation date, etc.): once per (company, flag type)
Description now shows "(X roles)" when multiple instances exist.
