fix: 계정 삭제 시 대상 farm 노드(node_name)를 config-server에 전달

[yoon6yo]

Summary

config-server의 DELETE /accounts/users/<username>에 node_name 쿼리 파라미터가 추가됐는데(admin_infra PR #138), admin_be가 실제로 넘기지 않으면 효과가 없어서 이어서 수정했습니다.

• RequestExpiryService(만료 정리), AdminUserService(관리자 수동 삭제/유저 탈퇴 일괄 정리): 기존 Request.getNodeName()을 그대로 사용.
• AdminRequestCommandService의 승인 실패 보상 트랜잭션:
  • Pod 생성 자체가 실패한 경우 — PodService.createPod가 config-server 에러 응답 바디에서 node 필드(admin_infra PR #138에서 추가)를 파싱해 PodCreationFailedException으로 들고 오도록 확장.
  • Pod는 성공했는데 이후 DB 반영이 실패한 경우 — 이미 있는 CreatePodResponseDTO.node() 사용.

node를 못 구하면 null로 넘어가고, config-server는 하위 호환으로 기존처럼 전체 farm을 훑습니다 — 동작이 깨지지 않고 좁혀지지만 않을 뿐입니다.

의존성: admin_infra PR #138(config-server의 node_name 파라미터 + 에러 응답 node 필드)이 먼저 배포되어야 실질적 효과가 있습니다. 그 전에 이 PR만 배포돼도 하위 호환으로 안전합니다(node가 항상 null인 것처럼 동작).

Test plan

• ./gradlew compileJava 통과
• pod 생성 실패 유도 후, 보상 트랜잭션이 실패 노드로 좁혀서 계정을 정리하는지 확인 (admin_infra PR [fix] #137 fix change request fetch error #138 배포 후)
• node 파싱 실패 시 하위 호환(전체 farm 훑기)으로 안전하게 넘어가는지 확인
• 만료 정리/관리자 수동 삭제 경로가 기존과 동일하게 동작하는지 확인

Summary by CodeRabbit

• Bug Fixes
  • Improved cleanup when pod creation or database updates fail by targeting the affected farm node.
  • Ubuntu account deletion now uses the request’s node information when available, reducing unnecessary cleanup across other nodes.
  • Expired and bulk-cleanup requests now preserve node details during account removal.

Capture pod failure node src/main/java/DGU_AI_LAB/admin_be/domain/requests/service/PodCreationFailedException.java, src/main/java/DGU_AI_LAB/admin_be/domain/requests/service/PodService.java	Pod creation failures now parse and retain the target node in PodCreationFailedException.
Add node-aware account deletion src/main/java/DGU_AI_LAB/admin_be/domain/requests/service/UbuntuAccountService.java	Ubuntu account deletion now accepts an optional node name and adds it to the request URI when provided.
Forward nodes through approval compensation src/main/java/DGU_AI_LAB/admin_be/domain/requests/service/AdminRequestCommandService.java	Approval compensation passes the failed node or created pod node to Ubuntu account cleanup.
Forward nodes through request cleanup src/main/java/DGU_AI_LAB/admin_be/domain/requests/service/RequestExpiryService.java, src/main/java/DGU_AI_LAB/admin_be/domain/users/service/AdminUserService.java	Expired-request and administrative cleanup pass each request’s node name to Ubuntu account deletion.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 8a10a

Account deletion now targets a farm node, but node names containing URI-reserved characters can make deletion requests malformed or change their query parameters. Encode the node parameter before merge.

Encode nodeName as a URI variable.

UbuntuAccountService passes a concatenated URI to the configWebClient WebClient.uri(String) method. Reserved characters in Request.nodeName can change the query or invalidate the request. Build node_name with a URI template variable and expand it strictly, rather than concatenating the value.
