상단 토글(주간/월간)로 보기 전환. 월간은 전통 달력 그리드(주×요일).

- scheduleDate: firstOfMonth/addMonths/monthLabel/monthGridWeeks(+MonthDay) 추가
- schedule.store: viewMode + anchor 기반으로 주간/월간 범위·라벨·네비 일원화
  (goPrev/goNext 가 모드별로 주/월 이동, setViewMode 시 범위 재조회)
- ScheduleMonthGrid: 주 단위 다중일 막대(레인 패킹) + 초과 '+N',
  카테고리 색·유형 필터·오늘/주말/이전·다음달 표기, 막대 클릭 시 상세 패널
- SchedulePage: SegmentedTabs 토글 + 주간/월간 조건부 렌더
