feat: 그룹 유량제어 메트릭 API 추가

- GroupMetricDTO: allowed/rejectedPerSecond/rejectedThreshold/rejectRatio 등 - InflowGroupMetricService: DualInflowControlManager를 통한 메트릭 조회·초기화 (getManager() protected 처리 — 단위 테스트 서브클래싱 지원) - InflowGroupMetricController: 4개 엔드포인트 GET /{groupId}/metric, GET /metric POST /{groupId}/metric/reset, POST /metric/reset - 단위 테스트 2종 (Service 16건, Controller 8건) 전체 통과 - elink-online-common 서브모듈 포인터 업데이트 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
