트래픽 차감은 TrafficDeductOrchestratorService를 중심으로 **개인풀 우선 전략**을 따릅니다. 다중 인스턴스 환경에서의 동시성 이슈를 원천 차단하기 위해 원자성(Atomicity)이 보장되는 **Redis Lua Script**를 활용합니다.

1. **개인 데이터 우선 연산 (`INDIVIDUAL`):** 요청된 트래픽(예: 500MB)을 먼저 사용자의 개인 데이터 풀에서 차감 시도합니다.
2. **잔여량(Residual) 위임:** 개인 풀 잔여량이 부족해 `NO_BALANCE` 상태가 반환되면, 미처리된 잔여 트래픽을 계산합니다.
