(bug): Warn users that SendWyre is US non-credit only.

Summary

@brianhatchet has chatted with SendWyre's team regarding this - they have clarified that they do not accept credit cards, and European customers are not supported yet (but they are working on this).

Logging this as a bug in the UX rather than a feature, because it is an oversight causing confusion to users.

Steps to reproduce

1. Buy tokens at https://www.minds.com/tokens

Platform information

Cross platform

What is the current bug behavior?

User is misdirected.

What is the expected correct behavior?

User should see these restrictions.

Relevant logs and/or screenshots

(Paste any relevant logs - please use code blocks (```) to format console output, logs, and code as it's very hard to read otherwise.)

Possible fixes

We need to add a warning of some sort, maybe just a bit of clear text.
