Register ChatClientAccessor and add related tests

Added transient registration for IChatClientAccessor<> in AbpAIModule. Updated ChatClientAccessor to implement ITransientDependency and removed TryRegister from dependency attribute. Introduced unit tests for ChatClientAccessor resolution and behavior. Adjusted MockChatClient's StreamingResponseParts constant for test consistency.
