Replace `console.log` with `Alert`s so if something goes wrong with media selection/processing/uploading we can at least give the user an indication that the operation failed.
Proper error handling would include cleaning up temporary files + creating a media mission report, but deferring that for now.
NOTE: Currently if `dispatchActionPromise` of `updateUserAvatarCall` fails it'll fail silently. One possibility could be to wrap the call like we do in `siwe-login-form` to introspect (see below), or we could have a `useEffect` that `Alert.alert(...)`s if `loadingStatus === 'error'`?
