hbyang c8dc68536e [feat] solution: SNS 연동을 '내 사이트' 한 자리로 — 연결은 한 번, 게재는 사이트마다
연결 버튼이 발행 모달 안에 있었다. 그런데 계정은 `user × provider` 하나다(표도 그렇게 생겼다)
— 버튼이 사업장 화면에 있으면 사장님은 **업장마다 연결해야 하는 줄 안다.** 사장님 지적:
"여기 내 사이트에 sns 연동 하나 두고 연동해두고, 사이트 발행 후 게재하는 형식으로".
화면이 데이터 모양을 그대로 말해야 한다 — 연결은 한 번, 게재는 사이트마다다.

- `GET /v1/social/account` 신설: 연결 상태만 준다. 사업장을 고르지 않아도 답할 수 있어야 하는
  값인데, 지금까지는 `/place/{id}` 안에만 있어서 사이트를 하나 고르기 전에는 물어볼 수 없었다
- features/social/SocialConnectionCard: '내 사이트' 목록 위의 연동 카드
  (@핸들 · [연결] · [다시 연결] · [연결 해제]). 앱 자격증명이 없으면 **아무것도 안 그린다** —
  누를 수 없는 버튼을 세우면 사장님에게는 고장난 화면이고 우리에게는 문의가 된다
- SocialPanel(발행 화면)에서 연결·해제 버튼 제거. 대신 계정이 없으면 "막다른 문구"가 아니라
  **갈 곳**을 알린다 — [내 사이트] 로 보낸다. 연결 전에도 소개글 복사는 된다
- docs/SOCIAL.md: 사장님 흐름을 '연결(한 번) / 게재(사이트마다)' 로 다시 씀

검증: SNS 테스트 14건 통과 · frontend tsc·eslint 통과. 로컬에서 임시 자격증명으로 카드가
켜지는 것과 인가 URL 조립을 확인하고 값을 되돌렸다(지금은 connection_enabled=false 로 안 뜬다)
