Use linktarget table instead of categorylinks.cl_to for MW 1.45+ compatibility

[hexmode]

MediaWiki 1.45+ changed the categorylinks table schema to use the linktarget table instead of storing category names directly in cl_to. This commit updates all queries to join with the linktarget table and use lt_title instead of cl_to.

Changes:

• Query.php: Updated all category-related queries to join linktarget
  • _addcategories, _articlecategory, _category, _notcategory
  • _ordermethod (category case), getSubcategories
  • buildAndSelect (categories goal)
• Article.php: Updated to read lt_title from query results
• Parse.php: Updated categories goal to use lt_title
• CreateView.php: Updated dpl_clview VIEW to use linktarget
• ArticleTest.php: Updated test fixtures to use lt_title

All joins use the pattern: cl_target_id = lt_id AND lt_namespace = NS_CATEGORY
