feat: 작업일정 기간 기반 + 프로젝트 연결

- partner_schedules: work_date → start_date/end_date 기간 기반으로 변경
- project_id 컬럼 추가 (projects 테이블 연결, 선택사항)
- 프로젝트 조회 API 추가 (GET /projects/active)
- 일정 조회 시 기간 겹침 조건으로 필터링
- 체크인 시 기간 내 검증 추가
- 프론트엔드: 시작일/종료일 입력 + 프로젝트 선택 드롭다운
- 마이그레이션 SQL 포함 (scripts/migration-schedule-daterange.sql)
