Introduce an HTMX-driven continents results component and refactor the continents page/JS to load/filter results dynamically. Added Continents::component_continent_results() and a new view (continents/component_results.php) which renders the chart/table container and exposes filter params via data attributes. Updated application/views/continents/index.php to use a filter card with an HTMX-enabled form that posts to the new component endpoint and injects results into #continentResults. Reworked assets/js/sections/continents.js to centralize AJAX logic into continentsRender(), add setContinentsLoading(), handle HTMX afterSwap to initialize results, improve error/info messaging, and implement a JS reset button that triggers an HTMX submit. Overall this enables incremental loading of continent stats and simplifies the previous full-form AJAX flow.
