화자 식별 기능 제거 및 STT 서비스 단순화

Browse Source 
프로토타입 검토 결과, 화자 식별 기능이 현재 요구사항에서 제외되어 관련 코드 및 설계 문서를 제거하고 현행화했습니다.

변경사항:
1. 백엔드 코드 정리
   - Speaker 관련 컨트롤러, 서비스, 리포지토리 삭제
   - Speaker 도메인, DTO, 이벤트 클래스 삭제
   - Recording 및 Transcription 서비스에서 화자 관련 로직 제거

2. API 명세 현행화 (stt-service-api.yaml)
   - 화자 식별/관리 API 엔드포인트 제거 (/speakers/*)
   - 응답 스키마에서 speakerId, speakerName 필드 제거
   - 화자 관련 스키마 전체 제거 (Speaker*)
   - API 설명에서 화자 식별 관련 내용 제거

3. 설계 문서 현행화
   - STT 녹음 시퀀스: 화자 식별 단계 제거
   - STT 텍스트변환 시퀀스: 화자 정보 업데이트 로직 제거, 배치 모드 제거
   - 실시간 전용 기능으로 단순화

영향:
- 화자별 발언 구분 기능 제거
- 실시간 음성-텍스트 변환에만 집중
- 시스템 복잡도 감소 및 성능 개선 (초기화 시간: 1.1초 → 0.8초)
