* refactor: introduce a generic taxonomy widget and refactor existing category and tag cloud widgets to use it.
* feat: Implement optional title linking for taxonomy widgets and enable parameter customization for taxonomy partials.
* refactor: remove fallback to taxonomy page title for widget display
Because this field always exists. I think it's better to let user customize via widget params
* Update layouts/_partials/widget/taxonomy.html
* refactor: check for .Params.taxonomy existence before accessing
