refactor: portfolio → personal 리네이밍 + Blog/Todo 통합

- portfolio/ 디렉토리를 personal/로 리네이밍
- lotto-backend의 Blog/Todo 라우트·CRUD를 personal 서비스로 이전
- lotto-backend에서 Blog/Todo 코드 제거 (DB 테이블 스키마는 유지)
- nginx: /api/todos, /api/blog/ 라우팅을 personal로 추가
- docker-compose: portfolio → personal 서비스 변��
- deploy 스크립트: portfolio → personal 반영

데이터 마이그레이션은 배포 후 NAS에서 별도 수행 필요:
1. cp data/portfolio/portfolio.db data/personal/personal.db
2. sqlite3 data/lotto.db ".dump todos" | sqlite3 data/personal/personal.db
3. sqlite3 data/lotto.db ".dump blog_posts" | sqlite3 data/personal/personal.db
