This PR updates the initial users migration in-place (replacing the existing name column with first_name/last_name). If anyone has already run the original migration, php artisan migrate will not apply this change, leaving their DB schema out of sync and causing runtime/test failures. Prefer adding a new migration that adds first_name/last_name, backfills from name, then drops name (or clearly document that contributors must migrate:fresh).

Suggested change

	$table->string('first_name');
	$table->string('last_name');
	$table->string('name');

Please update the issue reference (or PR title/description) so the PR is linked to the correct work item.
