Add support for booking_rules.txt to gtfs-schedule module

[Copilot]

• Create BookingRule.kt file with the data class and enum types
• Create BookingRuleTest.kt with unit tests
• Update common.kt to replace BookingRule placeholder type
• Add booking_rules.txt to ProducerTest TODO list (no sample data available)
• Run tests and verify everything works
• Run linter and fix any issues
• Fix prior_notice_duration fields to use WholeMinutes
• Resolve merge conflicts with main branch

Original prompt

Please add support for booking_rules.txt to the gtfs-schedule module. Use gtfs.org/documentation/schedule/reference#booking_rulestxt as a reference. Follow all existing patterns, especially the data types used and the tests. Remember to uncomment the relevant lines in producertest when you've added the model, or add it to the list at the bottom if none are available.

These should be WholeMinutes

Fixed in bb28fc8. Changed WholeSeconds to WholeMinutes for prior_notice_duration_min and prior_notice_duration_max fields.

Merge conflicts resolved in f0916b8. Merged main branch which added Shape, LocationGroup, LocationGroupStop, Transfer, and Frequency models. The TODO list in ProducerTest now includes both booking_rules.txt and frequencies.txt.
