Important: #109147 - Move link validator module to Link Management group 

Description 

The link validator module (Check Links) has been moved from the Status / Info module group (content_status) to the Link Management module group (link_management), alongside Redirects and QR Codes.

Since the Link Management parent module does not provide a page tree navigation component, the link validator module now brings its own navigationComponent to retain the page tree.

Additionally, the module identifier has been changed from web_linkvalidator to linkvalidator_checklinks.

Impact 

The link validator module now appears under Link Management in the backend module menu instead of Status / Info.

An upgrade wizard ensures that backend users and groups with web_linkvalidator permissions are migrated to linkvalidator_checklinks and automatically receive access to the link_management parent module.
