Move CV matcher repositories from cv-matcher-api to cv-matcher-data

- Move IAiPromptsRepository, EfAiPromptsRepository to cv-matcher-data/Repositories
- Move IMatcherRepository, EfMatcherRepository to cv-matcher-data/Repositories
- Add cv-matcher-api-models ProjectReference to cv-matcher-data.csproj
- Delete cv-matcher-api/Data folder (all data access now in cv-matcher-data)

Pattern: cv-matcher-api (logic) → cv-matcher-data (repositories, EF entities, migrations)
Aligns with rag-api → rag-data consolidation
