Several improvements and refactorings are needed for managing stream speakers. The following tasks outline the required changes:

Tasks

   • Implement StreamSpeakerDto, AddStreamSpeakerDto, and UpdateStreamSpeakerDto for handling stream speaker-related actions.

2. Code Cleanup:

   • Remove @ToString annotations from classes where not applicable.
   • Replace emptyList() with List.of() in mapper classes.

3. Country API Access:

     • GetStreamSpeakersResponse
     • StreamSpeakerResponse
     • AddStreamSpeakerResponse
     • UpdateStreamSpeakerResponse

6. Implement StreamSpeakerMapper:

   • Develop StreamSpeakerMapper to map StreamSpeaker domain entities to StreamSpeakerResponse objects.

7. Add Member Existence Validation:

   • Add MemberRepository.existsByMemberId() method to support the validator.

8. Update StreamSpeakerService:
