Sends a confirmation email (best-effort, fire-and-forget SMTP via mailer.py) on booking creation, with a manage-booking link embedding the ticket-2 signed token. Adds /manage/<token>, a stateless cancel/reschedule page that reuses the existing slot-picker against booking_api's create/cancel/reschedule API, distinguishing an invalid/expired link from an already-cancelled one. Sender address uses the client's own domain when configured, falling back to a mivanchenko.de address otherwise. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
