feat: 시세 자동조회·퇴직연금 평가액·게시판 카테고리·태그 정렬·계좌번호 암호화

- 투자: 종목코드로 현재가 시세 자동조회(StockQuoteService, 투자탭/포트폴리오 진입 시 갱신)
- 투자: 퇴직연금 등 평가액 직접입력형 계좌(currentValue 활성화, manualValuation)
- 게시판: community/saving/tips 카테고리 분리(post.category + 목록 필터)
- 태그: 순서 변경(account_tag.sort_order, /tags/reorder)
- 보안: 계좌번호 AES-256-GCM 암호화 저장/복호화(EncryptedStringTypeHandler, account_number VARCHAR(255))
  키는 서버 .env ACCOUNT_CRYPTO_KEY 로 주입(미설정 시 평문 통과)
