Changes:

• Refactored _getDateText method to convert dates to grid timezone before formatting
• Removed unused _getStartDate and _getEndDate helper methods
• Added TestCafe test for appointment collector timezone handling

The direct destructuring of startDate and endDate from the appointment object bypasses the data accessor system. The old implementation used this.instance._dataAccessors.get('startDate', appointment) and this.instance._dataAccessors.get('endDate', appointment), which correctly handles custom field name mappings when users configure options like startDateExpr and endDateExpr. Direct property access will break when custom field names are used. The code should use the data accessors instead.

Suggested change

	const { startDate, endDate } = appointment;
	const startDate = this.instance._dataAccessors.get('startDate', appointment);
	const endDate = this.instance._dataAccessors.get('endDate', appointment);
