AX Agent 내부 설정 MCP 서버 관리와 대화 스타일 섹션 복구

- AX Agent 내부 설정 공통 탭에 대화 스타일 섹션 제목을 복구해 문서 형태/디자인 스타일 저장 항목을 명확히 노출

- 스킬 탭 MCP 서버 영역에 서버 추가 버튼을 복원하고 목록 카드에서 활성화 전환과 삭제를 바로 처리하도록 보강

- 오버레이 저장 경로를 그대로 사용해 내부 설정에서 변경 즉시 저장되도록 유지

- README와 DEVELOPMENT 문서에 2026-04-06 00:45 (KST) 기준 이력 반영 및 Release 빌드 경고 0 오류 0 확인
