The Results table had a unique constraint on (CvDocumentId, JobDocumentId) but the code
expects uniqueness on (CvDocumentId, JobDocumentId, Language). When matching the same CV
against the same job in different languages, this caused duplicate key violations.
Changes:
- Updated CvMatcherDbContext to define 3-column unique index including Language
- Generated proper EF Core migration to drop 2-column index and create 3-column index
- Updated ModelSnapshot to reflect new 3-column index definition
- Added exception handling in SaveMatchAsync to gracefully handle any race conditions
where duplicate key violations could occur between the existence check and insert
The migration will be automatically applied on container startup via db.Database.Migrate().

- Move IRagRepository, EfRagRepository, and VectorSerializer from rag-api/Data to rag-data/Repositories
- Add rag-api-models ProjectReference to rag-data.csproj for model type availability
- Delete rag-api/Data folder (no longer needed; all data access is now in rag-data)
- This aligns RAG with email-api and other services: all data code in the data project
Pattern: rag-api (API logic) → rag-data (repository, EF entities, migrations)

Each DbContext now explicitly configures its migration history table to use
the schema-qualified name pattern [schemaName].[_Migrations]:
- [cvMatcher].[_Migrations] for CvMatcherDbContext
- [emailApi].[_Migrations] for EmailApiDbContext
- [cvSearch].[_Migrations] for CvSearchDbContext
- [rag].[_Migrations] for RagDbContext
- [myAi].[_Migrations] for MyAiDbContext
This is done via OnConfiguring() with UseSqlServer().MigrationsHistoryTable(name, schema).
Removed incorrect rename migrations that were created due to misunderstanding
of the proper EF Core configuration approach.
