Refactor using directives and remove conversion methods

Removed TinyHelpers.AspNetCore.Swagger directive from Program.cs as its functionality is no longer needed. Added TinyHelpers.EntityFrameworkCore.Converters directive to PropertyBuilderExtensions.cs to utilize its features. Removed HasDateOnlyConversion and HasTimeOnlyConversion methods from PropertyBuilderExtensions class, indicating these conversions are no longer required or have been relocated.
