Refactor CoreDbContext to use C# 12 primary constructor

Refactored the `CoreDbContext` class to leverage the new C# 12
primary constructor syntax, simplifying the class definition
and reducing boilerplate code. Updated XML documentation to
include a `<remarks>` section for additional context. Removed
the explicit constructor definition and its associated
documentation as it is no longer needed. No changes were made
to the `Customers` property.
