feat: Agregar migración completa de sistema de disponibilidad

- Crear tablas booking_blocks y staff_availability - Crear funciones RPC: check_staff_work_hours, check_staff_availability, get_available_staff, get_detailed_availability - Agregar campos de horario a staff (work_hours_start, work_hours_end, work_days, is_available_for_booking)
