move constructor to setupBilling function itself. We don't want to create singleton instance on memory directly. Export class itself instead.

pass all models here instead of subscription model alone. In future multiple db models update will be handled on webhook handlers. Change accordingly on each handler as well.

verification data should be fetched from database post webhook handler is executed. Since webhook handler will update db records. Fetch data from db instead of this. Update for the same on all test cases.

why we need function here? why can't we just create new instance directly? Think properly before adding extra unnecessary steps.
