Creates a new event in your school's system.

What this endpoint does:

• Creates a new event with the provided information
• Creates classrooms if they don't exist in the system
• Associates students and professors with the event
• Sends push notifications to students if the event already exists, is updated and is within the next 3 days
• Handles errors gracefully if some students or professors aren't found

Automatic features:

• Classroom creation: If you specify a classroom name that doesn't exist, it will be automatically created
• Smart notifications: Students receive push notifications for updated events happening within the next 3 days
• Error resilience: The event is still created even if some student/professor IDs are invalid

API ID Mode: Use this when your external system has its own user IDs that differ from Edusign's internal IDs.
