Stripe integration: subscriptions, billing dashboard & webhook h

Task: connect Stripe to a SaaS product — subscriptions,
auto-renewal, access management via webhooks.

What was built:
— Stripe Checkout for subscription plans (monthly/yearly)
— Webhook handler: payment_succeeded → access activation
— Event deduplication via Stripe-Signature verification
— Stripe Customer Portal — users manage their own subscriptions
— Billing dashboard: status, next charge date, payment history
