fix(v0210): importNote 가 capture revision 을 함께 INSERT (final review fix)

final code review 발견: F5 import 후 first user edit 시 import 시점 본문이
note_revisions 에 없어 history 에서 사라지는 회귀. importNote transaction 안
INSERT 추가 (createdAt = edited_at).

부수 작업: ImportNoteInput / importNote 의 "raw_text invariant guard" 주석을
v0.2.10 의 'fork-on-id-collision (sync determinism)' 정확한 의미로 갱신.

테스트 +2 — insert path / fork path 모두 capture revision 검증.
