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.
