Odd and even week schedules available in API

In the v2 API, the contract entity does not provide alternating schedules for even and odd weeks. This makes it impossible for us to correctly process contracts where working hours differ per week type.

Many organizations use alternating schedules. Without access to both even and odd week data, our capacity, overtime, and planning reports are incomplete and do not match the actual situation.

Add a schedule attribute to the contract entity returned by Get user by Id (https://v2.api.timechimp.com/users/${id}) that includes both evenOrDefaultWeek and oddWeek.
