chore: PHPStan fixes for always-false instanceof and redundant nullsafe

* TypeBuilder: `$operation instanceof Query` is always false inside the
  `$wrapData` block since `$wrapData` requires Mutation|Subscription
* PartialCollectionViewNormalizer: inside `if ($isPaginatedWithCursor)`,
  `$operation` is narrowed to non-nullable HttpOperation — use `->` not `?->`
