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`.
Added `EndpointParamsApiTests` to validate the `EndpointParams`
API functionality. Introduced tests for dependency injection
resolution, `CreateAsync`, `UpdateAsync`, and `DeleteAsync`
methods to ensure proper behavior, including exception handling
and HTTP method verification. Utilized scoped clients for
resource management and introduced payload DTOs for API
operations.
