설정 fan-out 통합과 AX Agent 대기열 상태 분리 정리

- AX Agent가 SettingsService 변경 이벤트를 직접 구독해 메인 설정과 AX Agent 설정 어느 경로에서 저장하더라도 테마, 모델, 권한, 데이터 활용, composer, 대기열 UI를 즉시 다시 읽어오도록 fan-out 경로를 통합함
- AX Agent 설정 저장 경로와 구형 Agent 설정창에서 표현 수준을 rich로 덮어쓰던 처리를 제거해 풍부하게/적절하게/간단하게 설정이 유지되도록 보정함
- DraftQueue 패널을 실행 중/다음 작업/보류/완료/실패 개별 섹션으로 재구성해 queue state를 더 빠르게 파악할 수 있게 정리함
- README, DEVELOPMENT, AGENT_ROADMAP 문서 이력을 2026-04-04 23:23 (KST) 기준으로 갱신함
