Subject: [PATCH] feat: Handle 202 Accepted from /charge endpoint

The auth service now returns HTTP 202 for async payments that are accepted
but still processing. This change treats 202 the same as 200 (success).

- 200 = synchronous payment completed
- 202 = async payment accepted (balance checked, executing in background)
