test(intake): pin wall-clock on idempotency tests

Both 'is idempotent on a second pass' and 'does not double-mint when today's rows already exist' hard-coded the scheduledFor to 2026-05-21T05:00Z while the route's projection uses new Date(). On 2026-05-22 the projected day diverged from the existence-row date and createMany fired, breaking the regression guard. vi.setSystemTime pins both ends to the same calendar day.
