farm 마이그레이션 사고(-migrated 접미사 붙이던 수동 DB 복구) 때 만들어진 행 중 일부는 Request.ubuntu_username/uid/gid만 채워지고 User 쪽 컬럼은 갱신되지 않은 채 NULL로 남아있었다. 오늘 deleteUbuntuAccount를 User 테이블 조회 기반으로 바꾼 뒤로는 이런 행을 관리자가 삭제하려 하면 "엔티티를 찾을 수 없음"으로 막혔다(실제 DB 조회로 재현: user_id 5/8의 ubuntu_username/uid/gid가 전부 NULL인데 request_id 64/65/66은 FULFILLED 상태로 실제 uid/pod/node를 갖고 있었음). User 테이블 조회로 못 찾으면 같은 유저네임을 가진 살아있는 Request의 소유자로 한 번 더 찾도록 폴백을 추가했다. User에 UID/GID가 아예 없으면 config-server 계정 삭제까지는 못 가지만(release 단계에서 스킵), Pod 삭제와 Request DELETED 전환은 정상적으로 이뤄진다. 재현 테스트 추가, 전체 592개 테스트 통과.
deleteUbuntuAccount(username)가 User 테이블에 UID/GID가 없는 레거시 데이터를 Request 기준으로 찾아 소유자를 정리하는데, User 쪽에 UID/GID를 복구하지 않으면 releaseUbuntuAccount가 hasUbuntuAccount()==false로 판단해 실제 config-server 계정 삭제 호출을 건너뛰었다 — Pod/DB 정리는 되지만 farm 노드의 리눅스 계정은 그대로 남는 상태가 됐다. Request에 남아있는 실제 UID/GID(양수인지도 검증)로 User를 먼저 복구한 뒤 정리 흐름을 태우도록 수정. 이 파일의 다른 모든 assignUbuntuAccount 호출 지점(AdminRequestCommandService 등)과 동일하게 findByIdForUpdate로 행을 잠그고 수정해, 동시 요청 간 준영속 상태 덮어쓰기를 방지했다.

Restore User.ubuntuUsername for the documented legacy state.
If User.ubuntuUsername is null, line 367 restores only UID/GID. releaseUbuntuAccount then reads a null username and skips the config-server deletion. The Linux account remains.
