Updates an existing event with new information.

What this endpoint does:

• Updates only the fields you specify (partial update)
• Creates new classrooms if they don't exist
• Intelligently manages student and professor associations
• Sends notifications to students for upcoming events (within 14 days)
• Handles errors gracefully if some student/professor IDs are invalid

Smart participant management:

• Replacement logic: When you provide a students or professors array, it completely replaces the existing list
• Adding participants: The system automatically determines who to add
• Removing participants: The system automatically determines who to remove
• Empty arrays: Send [] to remove all students or professors from the event

Automatic notifications: Students receive push notifications when dates, times, or locations change for upcoming events.

Partial updates: Only include the fields you want to change. Omitted fields remain unchanged.
