"""
Migration script to add manual breakfast configuration settings:
- resos_enable_manual_breakfast: Boolean flag to enable manual breakfast periods
- resos_manual_breakfast_periods: JSONB array of breakfast periods per day of week

This allows defining breakfast periods that are not in Resos (since breakfast bookings
are not taken through Resos) to properly categorize early morning restaurant tickets.

Format: [{"day": 1, "start": "07:00", "end": "11:00"}, ...] where day: 1=Monday, 7=Sunday

Run this script once after deploying the new code.
