fix: menu icons use FA6 for unmapped classes, query all MokoWaaS submenu items

- Helpdesk: fa-solid fa-handshake-angle (was icon-headphones, unmapped)
- .htaccess: fa-solid fa-file-code (was icon-file-code, unmapped)
- Query now finds ALL submenu items under the MokoWaaS parent menu,
  including those linking to com_plugins, com_installer, com_checkin, com_cache
