feat(admin): online-booking window UI in doctor weekly schedule

Add a نوبت‌دهی آنلاین card to the weekly-schedule tab: a toggle for
online_booking_enabled and a value+unit (هفته/ماه) booking window.
Hydrated from the schedule meta and sent in the weekly-schedule
POST/PATCH payload. Uses existing .input/.btn classes, RTL.
