fix: SiftingAppender 파일 락 및 on/off 제어 개선

- PatternLayoutEncoder를 buildAppender() 내부에서 appender별 독립 생성 (공유 인스턴스
제거)
   - SiftingAppender timeout 5분으로 단축 (기본 30분)
   - siftAppenderMap으로 appender 직접 관리, closeSiftAppender()로 즉시 파일 핸들 해제
   - siftEnabled 플래그 추가 및 txIdFilter에서 체크 (on/off 제어)
   - doConfigure() 기동 시 DB log.level 값으로 siftEnabled 초기화
   - FileLoggerPropertyChangeListener에서 SIFT log.level 변경 시
setSiftEnabled() 연동
