feat: KRW 가격 지원 및 GPU/G8/VPU 인스턴스 추가
## KRW 가격 기능 - pricing 테이블에 hourly_price_krw, monthly_price_krw 컬럼 추가 - 부가세 10% + 영업이익 10% + 환율 적용 (기본 1450원) - 시간당: 1원 단위 반올림 (최소 1원) - 월간: 100원 단위 반올림 (최소 100원) - 환율/부가세/영업이익률 환경변수로 분리 (배포 없이 변경 가능) ## GPU/G8/VPU 인스턴스 지원 - gpu_instances, gpu_pricing 테이블 추가 - g8_instances, g8_pricing 테이블 추가 - vpu_instances, vpu_pricing 테이블 추가 - Linode/Vultr 커넥터에 GPU 동기화 로직 추가 ## 환경변수 추가 - KRW_EXCHANGE_RATE: 환율 (기본 1450) - KRW_VAT_RATE: 부가세율 (기본 1.1) - KRW_MARKUP_RATE: 영업이익률 (기본 1.1) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
