task: #3610873 Repoint the events exposed form to the site default theme

Issue: https://www.drupal.org/project/varbase_events_base/issues/3610873

Problem

The events view hardcodes component_id: vartheme_bs5:views-exposed-filters on the exposed form of both events displays, with no repoint action. A site template built on a theme other than vartheme_bs5 must then repoint the exposed filters to its own theme itself.

Change

Add a setViewsComponentStyleTheme: {theme: default} config action on views.view.events. When the recipe is applied it repoints the view's component-driven style and exposed form onto the site's default theme. On plain Varbase (default theme vartheme_bs5) it is a no-op; on a site template that installs its own theme it repoints automatically, so the template no longer carries that override itself.

Note on effect

The exposed-form half of this repoint only takes effect once Varbase Recipes issue #3611878 is released: the currently released setViewsComponentStyleTheme repoints the view style but not the exposed form. Until that release, the Educare site template's explicit exposed-form repoint (Educare MR !10 (merged)) covers it. The style repoint takes effect with the already-released action.

AI-Generated: Yes (Used Claude Code to add the config action to recipe.yml.)
