fix(v032): NoteRepository.create now param + time-dep test flake fix

- create(input, now?: Date) signature 추가 (기존 setStatus/updateRawText 패턴 정합)
- NoteRevisions.test.ts 4 testcase v1 capture 시간 명시 주입 (2026-05-09T00:00:00Z)
- upsertFromSync.test.ts 2 testcase v1 capture 시간 명시 주입
- 시스템 시계가 2026-05-10T00:00:00Z 초과 시 DESC ordering 깨지던 회귀 회복

backlog: time-dependent flake (Cut F audit 발견)
