* fix: Show cancellation message when subscription is pending cancellation
When a subscription is cancelled via Stripe, the UI incorrectly showed
"Your contribution continues on..." instead of reflecting the cancellation
status. This fix adds tracking of `cancel_at_period_end` from Stripe webhooks
and displays "Your contribution ends on..." when a subscription has been
cancelled but is still active until the billing period ends.
