Every package now auto-books a consultation

When someone buys a package, the confirmation page offers instant calendar booking. It hits an availability API that checks my Google Calendar for free 45-minute slots over the next 30 days, then renders a date picker with only the times I am actually free. Pick a slot, confirm, and the booking endpoint creates a Google Calendar event with a Meet link and sends both of us an email. The whole thing chains together: Stripe payment completes, webhook fires, confirmation page loads, calendar slots appear, booking is made. No back-and-forth emails needed.
