Convert all hooks to OOP format and add tests

OOP hooks conversion

Converted all hook implementations across the main module and all 11 sub-modules from procedural .module functions to OOP classes using #[Hook] attributes, with #[LegacyHook] delegations in .module files for Drupal 10.6 backward compatibility.

Main module:

• src/Hook/ViewsFiltersSummaryHooks.php — hook_theme(), hook_views_data(), hook_views_filters_summary_filter_value_alter(), hook_views_filters_summary_plugin_alias()

Sub-modules converted (11):

• views_filters_summary_a11y — accessibility hooks
• views_filters_summary_address — address field support
• views_filters_summary_bef — Better Exposed Filters support
• views_filters_summary_commerce — Commerce integration
• views_filters_summary_cvfb — custom views filter block support
• views_filters_summary_eb — ECA/Block support
• views_filters_summary_eref — entity reference support
• views_filters_summary_search_api — Search API integration
• views_filters_summary_vcer — Views Contextual Entity Reference support
• views_filters_summary_verf — Views Entity Reference Filter support
• views_filters_summary_vsf — Views Selective Filters support

Each sub-module now has:

• A src/Hook/ class with #[Hook] attributes
• A .services.yml registering the hook class
• A .module file with #[LegacyHook] for Drupal 10.6 compatibility

Kernel tests (13 test methods, 254 assertions)

Added tests/src/Kernel/ViewsFiltersSummaryKernelTest.php covering the area plugin rendering logic:

1. testNoSummaryWithoutExposedInput — no summary when no filters active
2. testStringFilter — string filter value appears in summary
3. testStringFilterOperators — operator labels (!=, contains, starts, ends)
4. testBundleFilter — human-readable bundle label (not machine name)
5. testBooleanFilter — boolean shows "Yes"/"No" label
6. testTaxonomyFilter — taxonomy term labels (not tids)
7. testShowLabelsOption — filter label display toggle
8. testRemoveAndResetLinks — remove/reset link rendering
9. testFilterSelectionOption — limiting summary to specific filters
10. testPrefixAndSeparator — custom prefix and separator
11. testResultLabel — singular/plural result labels
12. testEmptyResults — empty results behavior with empty option
13. testGroupedFilter — grouped filter displays group item title

Also added the test infrastructure: views_filters_summary_test module with a test_vfs_summary test view (page display at /test-vfs-summary with exposed title, type, and status filters).

FunctionalJavascript tests (5 test methods, 48 assertions)

Added tests/src/FunctionalJavascript/ViewsFiltersSummaryJsTest.php covering all JavaScript interactions:

1. testSummaryRendersAndJsInitializes — navigates with active filter, verifies summary present, confirms JS removes the disabled class from remove links
2. testRemoveTextFilter — applies title filter via exposed form, clicks X remove link, verifies filter removed after page reload
3. testRemoveSelectFilter — applies type filter, verifies human-readable bundle label in summary, clicks X, verifies filter cleared
4. testResetAllFilters — enables reset link, applies title + type filters, clicks Reset, verifies all filters cleared
5. testAjaxRemoveFilter — enables AJAX on view, applies title filter, clicks X, verifies AJAX update without page reload (via Views DOM ID comparison)

Bug fix: missing core/once library dependency

During FunctionalJavascript test development, discovered that views_filters_summary.libraries.yml was missing core/once as a dependency. The JavaScript uses the once() function but did not declare this dependency. In production this usually works because other libraries (e.g. core/drupal.ajax) load core/once transitively. However, in minimal environments without AJAX, the once global is undefined and JavaScript initialization silently fails — the disabled class is never removed from remove/reset links, making them non-functional.

CI configuration

Updated .gitlab-ci.yml to run the new test suites.
