Updated all test methods to use asynchronous programming with
`async` and `await`, replacing synchronous calls with
`.GetAwaiter().GetResult()`. This improves readability and
aligns with modern C# practices.
Renamed test methods to reflect their asynchronous nature and
better describe their behavior. Updated exception handling to
validate HTTP methods and request URIs while maintaining
original assertions.
Applied changes consistently across multiple test classes,
including `CommonApiTests`, `EndpointAuthApiTests`,
`EndpointParamsApiTests`, `EndpointsApiTests`,
`ProfileApiTests`, `RecActionApiTests`, and `ResultApiTests`.
Introduced the `ResultApiTests` class to validate the behavior of the `Results` API client. Added test cases to ensure proper dependency injection, handle various API operations (`GetAsync`, `GetDynamicAsync`, `CreateAsync`, `UpdateAsync`, `DeleteAsync`), and verify expected outcomes such as exceptions, payload handling, and dynamic responses. Included necessary `using` directives to support the new tests.
