Add a Views exposed filters Single Directory Component

Problem/Motivation

Varbase renders a view's exposed filters through the components_exposed_form views exposed-form plugin (Varbase Components #3611182, merged to 4.0.x).

The base theme, Vartheme BS5, has gained a views-exposed-filters Single Directory Component in #3611865 (MR !189, merged to the 5.0.x branch).

Drupal SDC components are per-extension — a subtheme does not inherit the base theme's components into its own namespace. Vartheme BS5 Educare (vartheme_bs5_educare) is a starterkit-derived theme (base theme: false in its .info.yml, and composer.json does not require drupal/vartheme_bs5), so it does not pick up Vartheme BS5's component at all.

The Educare recipe repoints view component IDs onto the Educare theme via the setViewsComponentStyleTheme config action, so it will look for vartheme_bs5_educare:views-exposed-filters. Without a component of that name in this theme, the repoint has no target and the exposed filters render without the intended component wrapper.

Steps to reproduce

1. Install the Educare site template.
2. Repoint a view's exposed-filters style plugin onto vartheme_bs5_educare via the setViewsComponentStyleTheme config action.
3. Render the view.
4. The views-exposed-filters component does not exist in vartheme_bs5_educare, so the repoint has no target.

Proposed resolution

Add a components/organisms/views-exposed-filters/ Single Directory Component to Vartheme BS5 Educare, mirroring the contract shipped by Vartheme BS5 in #3611865 / MR !189: the same name, group: Views, noUi, use_in_views, the layout enum (inline / stacked), utility_classes, and the filters slot.

The component's own SCSS carries the Educare skin (search icon, input/select styling, labels, ghost Apply Filter / Reset actions), routed through this theme's Bootstrap tokens rather than hard-coded values. The new entry is registered in webpack.config.components.js and the compiled CSS is produced with the theme's real build (yarn components:build), never hand-written.

This mirrors a contract that has already shipped in Vartheme BS5; it does not need to wait on anything further.
