Hyungi Ahn 79c09cede4 feat: home-gateway 초기 구성 — Mac mini에서 GPU 서버로 전면 이전
OrbStack 라이선스 만료로 Mac mini Docker 서비스를 GPU 서버로 통합.
nginx → Caddy 전환, 12개 서브도메인 자동 HTTPS, fail2ban Caddy JSON 연동.

주요 변경:
- home-caddy: Caddy 리버스 프록시 (Let's Encrypt 자동 HTTPS)
- home-fail2ban: Caddy JSON 로그 기반 보안 모니터링
- home-ddns: Cloudflare DDNS (API 키 .env 분리)
- gpu-hub-api/web: AI 백엔드 라우터 + 웹 UI (gpu-services에서 이전)
- AI 런타임(Ollama) 내부망 전용, 외부는 gpu-hub 인증 게이트웨이 경유
