Improve UI/UX when users try to add an invalid card with Stripe

Summary: Ref T13244. See PHI1052. Our error handling for Stripe errors isn't great right now. We can give users a bit more information, and a less jarring UI.

Test Plan:
Before (this is in developer mode, production doesn't get a stack trace):

{F6197394}

After:

{F6197397}

- Tried all the invalid test codes listed here: https://stripe.com/docs/testing#cards
