fix(l10n): localize widget/complication placeholder sample labels

- placeholder()의 생 한국어 리터럴 6곳을 String(localized:)로: ③다짐 링·④다짐 현황·잠금화면 위젯의 spanLabel "오늘"(기존 키 재사용), 워치 목표/다짐 달성률 "목표"/"하루"(기존 키 재사용), 워치 현재 현황 샘플 "독서"(워치위젯 카탈로그 신규 1키 — en Reading/ja 読書, iOS 위젯 카탈로그와 동일 값)
- placeholder는 갤러리/로딩 스켈레톤 전용 경로라 타임라인 예산·버튼 반응성·갱신 경로 무영향 — ①⑤ 위젯 placeholder가 이미 쓰던 패턴과 동일
- 검증: Debug·Store·워치 3스킴 빌드 성공, 전 카탈로그 missing/stale 0
