Payment Link Emails & Checkout Improvements

## What's New MyDojang's billing system now includes **automatic payment emails** and a streamlined checkout experience for parents. ## Automatic Payment Emails When you assign a billing plan or create a payment link for an ad-hoc charge, the parent automatically receives an email with: - Direct link to complete payment via Stripe - Student name and plan details - Amount due and payment instructions ## Resend Payment Links Need to remind a parent? Click the **"Resend Email"** button on any pending payment to instantly re-send the payment link — no need to create a new charge. ## Improved Payment Confirmation After completing a Stripe payment, parents now see a **friendly confirmation page** that shows: - Student name - Billing plan details - Payment status and amount paid - Next steps No login required — parents can complete the entire payment flow from their email. ## Better Billing Overview The student detail page now displays **all active billing plans** (not just one) with a direct **"Manage Billing"** button for quick access to payment history and plan management.
