Pull request overview

This PR performs cleanup around Markdown rendering on the homepage and aligns a couple of DTO namespaces with their directory structure, while adding a regression test for blank-input handling.

Changes:

• Mark add_headers_anchors as safe HTML, suppress libxml warnings, and add an early return for blank input.
• Update the homepage Twig pipeline to remove unnecessary |raw and adjust filter order.
• Move DTO namespaces (RegisterFormDto, ListUsersActionDto) and update imports/usages accordingly; add a regression test case.

• After moving this DTO to App\Dto\Form\Type, @see FormAction no longer resolves (it will now point to App\Dto\Form\Type\FormAction). Import the controller (or use its FQCN) so the reference stays correct.
