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. Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
