Pull request overview

Refactors the commons standings widgets to the widget3 functional component system (Module:Widget/Component), replacing the older Class.new(Widget) pattern and moving HTML tag construction to Module:Widget/Html.

Changes:

• Converted Standings Swiss/Ffa, RoundSelector, PlacementChange, and MatchOverview to functional components returned via Component.component(...).
• Switched HTML widget imports from Module:Widget/Html/All to the widget3 tag module Module:Widget/Html.
• Inlined some previously-method-based helper logic (e.g., match result rendering and movement indicator selection).

nitpick: all Widget return types should be updated to VNode (or Renderable)
