[Bug] Direct url does not work RewriteBase is enabled

[luka-nextcloud]

Describe the bug
When htaccess.RewriteBase is set to /, direct urls to cards or boards that include /index.php/apps/deck/... do not automatically redirect to the cleaner /apps/deck/... format. Instead, they result in a blank page. This behavior differs from other apps like Files, which handle the redirection correctly.

To Reproduce
Steps to reproduce the behavior:

1. Enable URL rewriting by following the instructions at https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/config_sample_php_parameters.html#htaccess-rewritebase
2. Access a card/board with direction url that includes index.php

Expected behavior
The url should automatically redirect to the cleaner format without index.php
