name/email changes are not synchronized between supabase and stripe

[cgar420]

When you change the customers name or email on the /account page, it updates in Supabase, NOT in Stripe.

When you change the customers name or email on the Stripe dashboard, it sends a Webhook, but the response is always 400.

customer.update events are not part of relevantEvents and return a 400 error.

So its a combination of 2 problems:

1. We are updating the customer info on Supabase instead of Stripe - updating on Stripe will trigger webhook
2. We are not handling the customer.update webhook
