feat(sync): wire SyncService — tray '지금 동기화' + on-quit drain

- src/main/index.ts: SyncService instantiate with paths.profileDir + exportSvc
- 트레이 6번째 콜백 — 토스트로 not_configured / done / unchanged / failed 안내
- before-quit 훅에 sync drain 추가 (backup 완료 후, syncSvc.isConfigured() 인 경우만)
- src/main/tray.ts: 6번째 callback runSync, '지금 동기화' 메뉴 (내보내기/복원 다음)
