fix(schedule): give scheduleType a clean enum type for the host-access gate

createInsertSchema inferred scheduleType as a broadened union (drizzle-zod 0.5.1),
so passing input.scheduleType into assertHostScheduleAccess failed typecheck on a
cold build. Refine the insert schema's scheduleType to a plain z.enum and type the
helper param as the schedule enum.
