This patch adds a skippable unit test for the fi_FI locale to prove
that the patches work well for other locales that don't use
the default Unicode collation. It will run on koha-testing-docker,
but will be skipped on systems lacking it.
This patch also fleshes out the existing unit tests a bit more
to prove that the patches also improves the sorting of names
with diacritics generally. That is, the default Unicode sort
is better than the existing stringwise/bytewise sort even for
English and French locales.
Test plan:
0. prove -v t/Koha/SearchEngine/Elasticsearch/Search.t \
t/db_dependent/Search_FacetSorting.t

This follow-up adds two major enhancements to the locale-based facet sorting
implementation:
1. **System Preference Integration**
- Adds FacetSortingLocale system preference for configurable locale selection
- Dynamically detects available system locales using Koha::I18N
- Provides user-friendly dropdown with locale descriptions
- Supports both Elasticsearch and Zebra search engines
2. **Zebra Search Engine Support**
- Extends locale-based sorting to Zebra (in addition to existing Elasticsearch)
- Implements _sort_facets_zebra() function in C4::Search
- Maintains consistent Unicode-aware sorting behavior across search engines
Key Features:
- Dynamic locale detection via Koha::I18N::available_locales()
- Proper module architecture with comprehensive unit tests
- Clean fallback chain: preference → system LC_COLLATE → default
- Admin UI integration in System Preferences → I18N/L10N
- Universal facet sorting for international library systems
Test plan:
1. Apply patch and restart services
2. Install/run database update
3. Navigate to Administration → System Preferences → I18N/L10N
4. Verify "Sort facet names using" dropdown shows available system locales
5. Test facet sorting with different locales and both search engines
6. Run: prove t/Koha/I18N.t t/Koha/SearchEngine/Elasticsearch/Search.t t/db_dependent/Search_FacetSorting.t
