Fix: Sort language autocomplete results alphabetically with prefix ma…

[Saad259]

Closes #10765

The autocomplete_languages function in utils.py was yielding results in the order they were iterated from get_languages() rather than in a meaningful order. This PR collects all matches into a list first, then sorts them so that names starting with the search prefix rank above names that merely contain it elsewhere, with alphabetical ordering within each group.

Note: locale-aware collation (for correctly sorting translated language names for non-English users) is a known limitation. Implementing it safely in a concurrent web server would require a thread-safe i18n library like babel, which is not currently a dependency. This could be addressed as a separate issue. The docstring has also been updated to reflect the new correct output order.

Technical

Testing

1. Navigate to http://localhost:8080/languages/_autocomplete?q=eng&limit=10
2. Confirm "English" appears before "English, Middle", "English, Old", and "Creoles and Pidgins, English-based"
3. Test with other prefixes such as fr and ar to confirm consistent behaviour.

Screenshot

Not applicable, no UI changes to the autocomplete dropdown itself. JSON output before and after is documented in the linked issue.
