Restore checkout flow for unsubscribed users

handleClick now only opens the billing portal when isSubscribed is true, and performs no action for unsubscribed accounts. This breaks both visible upgrade entry points (Start Free Trial and dropdown Subscribe) because they still call this hook, so non-paying users cannot start a Stripe checkout session anymore.

Useful? React with 👍 / 👎.
