StripePlatformCardController has unhandled response cases

# Problem

Similar to the issue described in #1031, `StripePlatformCardController` has unhandled response cases, which will all render as a 500.

The difference is, in this case, they are not properly mapped in `CodeCorps.StripeService.StripePlatformCardService` either, so we need to map them there as well.

# Steps needed in order to provide a time estimate

We should consider splitting these into separate tasks

- identify all possible responses for `CodeCorps.StripeService.StripePlatformCardService.create`
- discuss if the responses should be mapped differently
- apply new mapping if any
- handle these responses in the controller/fallback controller
