StripePlatformCard updates StripeConnectCards on update

[joshsmith]

Problem

• When a StripePlatformCard is created, it should create StripeConnectCards on all StripeAccounts for which the User currently has a StripeConnectSubscription.
• When a StripePlatformCard is updated, it should update the StripeConnectCards in its has_many.

As with customers, we don't really update any of it yet. Maybe this should be marked lower priority?

[joshsmith]

@begedin we don't, but we need to respond to Stripe when it does. There are webhooks for this, where a card may become expired, for example. Or fail. Not sure without looking at the docs precisely.

A misunderstanding, then. Wasn't clear to me we need to handle a webhook for this. Sorry.

My mistake. I thought it was implicit from this but never made it explicit anywhere.
