동일 완료 시각의 선택 기준을 고정하세요.

같은 날짜에 여러 측정 그룹의 completedAt이 같으면 병합 함수가 second를 선택합니다. findCompletedMeasurementGroupsInPeriod 쿼리는 max(e.completedAt)만 정렬하므로 동률 행의 순서를 보장하지 않습니다. 따라서 캘린더 응답의 measurementGroupId가 달라질 수 있습니다.

completedAt이 같을 때 measurementGroupId를 보조 기준으로 사용하세요. 동일 날짜·동일 완료 시각의 두 그룹을 반환하는 테스트도 추가하세요. Collectors.toMap은 중복 키에 지정한 병합 함수를 적용합니다. (공식 문서)

In `@src/main/java/com/atmd/backend/domain/calendar/service/CalendarService.java`
around lines 106 - 108, Update the merge function used by Collectors.toMap in
the calendar response to compare measurementGroupId when completedAt values are
equal, selecting the deterministic group according to that secondary key while
preserving the existing latest-completion selection. Add a test covering two
groups on the same date with identical completedAt values and verify the
resulting measurementGroupId.
