💳 Upfront Payments for Self-Scheduled Sessions

We're adding the ability to require payment when a client books through self-scheduling. When enabled, clients enter their payment details at the time of booking, and the session is only confirmed once payment goes through. If payment isn't completed within the time window, the slot is automatically released back to your calendar.

This is especially useful for intake sessions, clients with a history of no-shows, or high-demand time slots where a missed appointment means lost revenue. You'll be able to turn this on per service, so it applies only where you need it.
