This pull request focuses on enhancing the handling of SQL Server exceptions in the project. The primary goal is to produce more useful and strongly typed exceptions, improving the debugging experience and error handling.

Improvements to SQL Server exception handling:

• docs/adr/20241118-produce-useful-sql-server-exceptions.md: Added a new architectural decision record (ADR) to document the decision to use strongly typed SQL Server exceptions.
• src/Infrastructure/DependencyInjection.cs: Imported the EntityFramework.Exceptions.SqlServer package and updated the AddInfrastructure method to use the exception processor for better exception handling. [1] [2]
• src/Infrastructure/Infrastructure.csproj: Added a new package reference for EntityFrameworkCore.Exceptions.SqlServer to the project file.
