fix(sync): replace iText logger with SLF4J, add batch query methods

Replace com.itextpdf.text.log.Logger/LoggerFactory imports with
org.slf4j equivalents in SyncTaskService and SyncUserInfoService.

Add batchFindUserInfoByStuUserIds and batchFindUserIdByUsernames
queries to replace N+1 loop patterns in user sync operations.
