BaseCrudApi is now defined as BaseCrudApi<TCreate, TUpdate, TDelete>,
with each CRUD method using its respective type parameter. This
improves type safety and clarity for API payloads. Method signatures
and XML documentation have been updated accordingly.
Introduce BaseCrudApi to encapsulate common CRUD logic for API resource classes. Refactor CommonApi, EndpointAuthApi, EndpointParamsApi, EndpointsApi, ProfileApi, RecActionApi, and ResultApi to inherit from BaseCrudApi, removing duplicated CRUD methods and constructors. This centralizes CRUD operations, reduces code duplication, and improves maintainability.
