When editing an existing draft submission via a token link, Webform pagination breaks. Specifically, the "Previous" button incorrectly appears on the first page of the form.

/admin/structure/webform/manage/test_page/results/submissions and click on the submission ID (using the token URL to edit the draft).The issue is caused by the following methods returning an integer instead of a string or NULL as expected. This breaks strict comparisons in Webform’s pagination logic:
\Drupal\webform\Utility\WebformArrayHelper::getFirstKey\Drupal\webform\Utility\WebformArrayHelper::getLastKey\Drupal\webform\Utility\WebformArrayHelper::getKey\Drupal\webform\WebformSubmissionForm::getCurrentPageThese functions should consistently return either a string key or NULL, but never an integer.
The solution is to update these methods to cast array keys to string where applicable, ensuring consistency with the expected return types declared in their docblocks and usage throughout Webform.

We can't start adjusting standard and shared code the WebformArrayHelper to fix pagination. We need to get the root cause and address the problem.
