ProgressSerializer attribute block arity mismatch with fast_jsonapi

What Happened#

2026-06-06 ~ 06-07 기간 동안 cupixworks-worker의 FinalizeTransferWorker에서 Progress 모델의 Elasticsearch 인덱싱 시 ArgumentError: wrong number of arguments (given 1, expected 0) 에러가 13회 발생했다. Transfer 작업 완료 후 Progress 레코드를 ES에 색인하는 과정에서 ProgressSerializer의 잘못된 attribute 선언(&:record_complete_at)이 fast_jsonapi의 arity 기반 dispatch 로직과 비호환하여 에러가 발생하는 latent bug이다.
