fix: if payment fails with stripe and then user corrects it their account doesn't update for an hour

[eseidel]

We're presumably missing some stripe hook to catch the payment complete/account status change notification and clear our redis cache for the account.

@eseidel which customer did this happen to? I've seen a couple reports of people paying an invoice very late after their subscription was cancelled. I believe this is WAI.

I believe this was the user to most recently report such: https://admin.shorebird.dev/users/9273 (internal link)

My understanding is that when stripe completes a transaction, it calls our webhook. I suspect there is a differnet type of message for paying an outstanding invoice that we don't immediately translate into a redis cache clear for their account, but could. 🤷
