Removal of label query parameter from connected accounts API

The label query parameter has been removed from the GET /api/v3/connected_accounts endpoint.

What's changing?

The label query parameter is no longer supported when listing connected accounts. This parameter was previously accepted but had no functional behavior since label ingestion was removed in an earlier update.

Impact

None - This is a cleanup change. The label query parameter was not performing any filtering since the underlying label ingestion functionality was already removed. If your code was passing this parameter, it was being silently ignored.

Migration

No action required. If your code was passing the label query parameter, you can safely remove it from your API calls.
