Independent content for Calendar Invitation and Email Confirmation

Currently, the Calendar Invitation and Email Confirmation share the same content field. Any change made to one is automatically applied to the other, making it impossible to have different text for each.

This causes the confirmation email to display the content twice once as part of the calendar invite header and once as the email body which looks unprofessional and confusing for clients.

Requested improvement: Allow separate, independent content fields for the Calendar Invitation and the Email Confirmation within the same booking type, so that each can be tailored appropriately for its purpose.
