Fix EZP-22767: Added ezcss_require when using autocomplete.

## Description
When autocomplete in a module is called from the new stack, js files included with ezscript_require were not loaded. This is fixed in https://github.com/ezsystems/ezpublish-kernel/pull/833

CSS files are also missing. In order to load them within a module, they need to be required within the page and not in the config files.

## Test
Manual test
