feat(proxy-input): 대리입력 리뉴얼 — 2단계 UI + UPSERT + 부적합

프론트엔드:
- Step 1: 날짜 선택 → 전체 작업자 목록 (완료/미입력/휴가 구분)
- Step 2: 선택 작업자 일괄 편집 (프로젝트/공종/시간/부적합/비고)
- 연차=선택불가, 반차=4h, 반반차=6h 기본값

백엔드:
- POST /api/proxy-input UPSERT 방식 (409 제거)
- 신규: TBM 세션 자동 생성 + 작업보고서 INSERT
- 기존: 작업보고서 UPDATE
- 부적합: work_report_defects INSERT (기존 defect 있으면 SKIP)
