feat: add Auto Check MH Payment toggle with weekly schedule

Adds a toggle behind the Go button on the Payments page to automatically run the MH batch payment check on a user-selected day of week and hour. Default is off.

- Schema: added autoMhCheckEnabled, autoMhCheckDayOfWeek, autoMhCheckHour to User model
- Backend: new mhBatchPaymentService (shared logic), GET/PUT /auto-mh-check-setting routes, hourly cron job that fires on matching day+hour
- Frontend: toggle + day select (Mon–Sun) + time select (hourly) that persist immediately to DB
