[Sentry] IllegalStateException: Already resumed, but proposed with update kotlin.Unit

Sentry Issue: [METAMASK-MOBILE-3Z6V](https://metamask.sentry.io/issues/6768249846/?referrer=github_integration)

```
IllegalStateException: Already resumed, but proposed with update kotlin.Unit

at kotlinx.coroutines.CancellableContinuationImpl.resumeImpl$kotlinx_coroutines_core(CancellableContinuationImpl.kt:521)

...

```

Start with the Sentry stack trace and inspect ActivityResultsManager in expo.modules.kotlin.activityresult, then follow the callback path through AppCompatActivityAware.kt and CancellableContinuationImpl.kt. Determine why the activity result is resumed more than once and verify the fix against the reported IllegalStateException.
