feat: dcy-003/004 토큰 surface 개편 및 daemon lifecycle 정책 구현 (BAT-006/007)

BAT-006 (REQ-016/017/018):
- client token 발급 경로 제거 (issue_client_token, POST /auth/tokens, 관련 스키마/테스트)
- service-token rotate unique index revoked_at IS NULL 조건 추가 (Alembic CONCURRENTLY 마이그레이션)
- POST /auth/service-tokens body daemon_id forward 누락 보정 (1-line fix)

BAT-007 (REQ-022/023):
- daemon deactivate 시 바인딩 service token 자동 revoke (CLI --force 옵션 + revoke_tokens_by_daemon_id)
- NULL daemon_id legacy token 진단 CLI (migrate-null-daemon --dry-run)
