Move the new "Multiple Schedule" integration into its own page so it doesn't conflict with the existing "Personal Schedule" implementation.

For now, the "Multiple Schedules" implementation will be its own separate controller/view/etc. until the feature is fully complete. Then, once other teams have migrated to the new "Multiple Schedules" implementation, we can begin to deprecate the old "Personal Schedule" implementation in favor of this new one.
