Previously, users received multiple emails after successful payment:
- One email per individual ticket (via orders_controller.rb)
- One order-level email with all tickets (via order.rb mark_as_paid!)
This resulted in N+1 emails for N tickets purchased.
Changes:
- Removed individual ticket email sending from orders_controller.rb
- Kept single comprehensive order email in order.rb
- Updated test to reflect that email failures don't prevent order completion
- Users now receive exactly one email with all tickets as PDF attachments
