composer 상태줄 언어와 상태 표현 통일

- 하단 composer 상태줄에서 모델·데이터 활용·권한·브랜치가 같은 문법으로 읽히도록 문구를 정리하고 모델 버튼 툴팁에 현재 서비스/모델 정보를 보강함

- 데이터 활용과 권한 칩에 상태 색상 기반 테두리와 설명 툴팁을 추가해 현재 모드 인지가 더 쉬워지도록 정리함

- README.md와 docs/DEVELOPMENT.md에 2026-04-05 00:52 (KST) 기준 이력을 반영함

- 검증: dotnet build src/AxCopilot/AxCopilot.csproj -c Release -v minimal -p:OutputPath=bin\\verify\\ -p:IntermediateOutputPath=obj\\verify\\ / 경고 0 / 오류 0
