security: 보안 강제 시스템 구축 + 하드코딩 비밀번호 제거

보안 감사 결과 CRITICAL 2건, HIGH 5건 발견 → 수정 완료 + 자동화 구축.

[보안 수정]
- issue-view.js: 하드코딩 비밀번호 → crypto.getRandomValues() 랜덤 생성
- pushSubscriptionController.js: ntfy 비밀번호 → process.env.NTFY_SUB_PASSWORD
- DEPLOY-GUIDE.md/PROGRESS.md/migration SQL: 평문 비밀번호 → placeholder
- docker-compose.yml/.env.example: NTFY_SUB_PASSWORD 환경변수 추가

[보안 강제 시스템 - 신규]
- scripts/security-scan.sh: 8개 규칙 (CRITICAL 2, HIGH 4, MEDIUM 2)
  3모드(staged/all/diff), severity, .securityignore, MEDIUM 임계값
- .githooks/pre-commit: 로컬 빠른 피드백
- .githooks/pre-receive-server.sh: Gitea 서버 최종 차단
  bypass 거버넌스([SECURITY-BYPASS: 사유] + 사용자 제한 + 로그)
- SECURITY-CHECKLIST.md: 10개 카테고리 자동/수동 구분
- docs/SECURITY-GUIDE.md: 운영자 가이드 (워크플로우, bypass, FAQ)
