Add isInvitation field on BilletBuyer to distinguish invitations from free billets

- isInvitation (nullable bool) on BilletBuyer instead of checking totalHT == 0
- Set isInvitation=true when creating invitation in controller
- Email subject/content based on order.isInvitation
- Invoice shows organizer as buyer when order.isInvitation
- Invitations list filtered by isInvitation=true
