Pull request overview

This PR updates the Scheduler component to better support legacy popup layouts with custom form configurations, particularly for React Storybook demonstrations. The changes ensure that the recurrence rule state is properly synchronized between the form and the recurrence form component, especially when toggling between "never" and recurring appointments.

Key Changes

• Made recurrenceRule property public in RecurrenceForm class to allow direct external access and manipulation
• Modified recurrence value saving logic to always save (removed conditional guard), ensuring state consistency
• Updated React Storybook with a comprehensive legacy popup example using a custom switch-based recurrence toggle

I suggest to add more tests:

• We have added code to preserve values in recurrence form for repeat end editors. So we need to test case when:

1. User opens recurrence form
2. Changes value for repeat end editors (both count and until)
3. User goes back to main form
4. User selects different frequency in repeat editor (not 'never')
5. User open recurrence form again
6. Check that values in count, until and repeat end values are preserved

• We added code to set 'disabled' to repeat end editors on content ready. We need to cover it with tests
