Update logic for setting active subscription status

Broaden the conditions for active subscriptions in the lemon-squeezy-webhook-handler.service. Now, subscriptions that are cancelled but still within their valid period (cancelAtPeriodEnd) are considered active. This helps prevent users from losing access to services until their current subscription period strictly ends.
