Deprecated `OC\Server::getL10NFactory` method removed leading to uncaught Exception

[edward-ly]

Describe the bug

Recently, nextcloud/server#58808 removed the long-deprecated OC\Server::getL10NFactory method, causing this error:

[index] Error: Call to undefined method OC\Server::getL10NFactory() in file '/var/www/html/apps-extra/app_api/lib/Controller/ExAppsPageController.php' line 120
	GET /index.php/apps/app_api/apps/list
	from 192.168.21.2 by admin at Apr 9, 2026, 11:46:36 AM

I believe OCP\L10N\IFactory is the equivalent class to use instead here?

Steps/Code to Reproduce

Navigate to the Apps page. A An error occurred during the request. Unable to proceed. error notification shows up.

Expected Results
