Introduce MassData feature with new API endpoints for querying and upserting records by customer name. Add DTOs, AutoMapper profile, MediatR CQRS handlers, repository pattern, and MassDataDbContext. Register new services in DI and add MassDataConnection to configuration. Upsert uses stored procedure. Enables full CRUD for Massdata via dedicated API.
Refactor ApplicationDbContext to use a configuration-driven approach for mapping view and column names, enabling dynamic mapping through appsettings.json. Add TableConfigurations classes, update DI registration, and include the necessary options package for configuration binding. This improves maintainability and flexibility for schema changes.
Refactored dependency injection by introducing AddApplication and AddInfrastructure extension methods for service registration. Moved DbContext and AutoMapper setup out of Program.cs to improve modularity and reusability. Added required NuGet packages to .csproj files.
