Summary of Changes

In ItemsModel inside populateState() the mod_menu language file load was placed before the menutype resolution logic that determines the final client_id. Moved it to after getUserStateFromRequest() so it uses the final resolved client_id.

Testing Instructions

Navigate to:
Menus -> manage > switch the filter/dropdown to Administrator
mow create a new menu with Preset set to "System Dashboard"

now look in Menus -> at the bottom you will see the custom admin menu you just created > click on it.

Actual result BEFORE applying this Pull Request

Titles show as raw language constants like MOD_MENU_CONFIGURATION, MOD_MENU_CLEAR_CACHE, etc. on first load. Refreshing the page fixes it.

Expected result AFTER applying this Pull Request

itles show correctly as "Global Configuration", "Clear Cache", etc. right away — no refresh needed.
