Summary

Add a checkbox in the Advance Publishing flow to control whether start time changes should be marked with the "change" label on Equipe Online.

Background

Related to: https://help.equipe.com/questions/6cb84839-bfe5-4912-9027-21f68faa9c16

Organizers frequently update start times before events. Currently, all start time changes are automatically marked with the "change" label online, which can make the schedule look messy for shows with many updates.

Proposed Solution

Add checkbox in Publish Advance:
- Label: "Show start time changes on Equipe Online"
- Default: Checked (current behavior)
- When unchecked: Publish updated start times without the "change" label

This allows organizers to publish start times without showing the "changes" label to the public, complementing the existing per-class "Clear Change" functionality.
