feat: eliminate htaccess.conf, move all URL routes to pp_routes (v0.329-0.330)

- Add category_id, page_id, article_id, type columns to pp_routes (migration 0.329)
- Move routing block in index.php before checkUrlParams() with Redis cache
- Routes for categories, pages, articles now stored in pp_routes instead of .htaccess
- Delete category/page/article routes on entity delete in respective repositories
- Eliminate libraries/htaccess.conf: generate .htaccess content entirely from PHP
- Move 32 static system routes (koszyk, logowanie, newsletter, AJAX modules, etc.)
  plus dynamic language/producer routes to pp_routes with type='system'
- Invalidate pp_routes Redis cache on every htacces() regeneration
