# Description of Changes
### Summary
- Added support for configuring UI languages via `settings.yml`
(`languages` field).
- Modified `LanguageService` to respect the configured languages, while
ensuring British English (`en_GB`) is always enabled.
- Updated Thymeleaf templates to dynamically display only the allowed
languages.
- Improved logging and refactored some list-to-set conversions for
better efficiency.
### Why the Change?
- Allows administrators to limit available UI languages instead of
displaying all detected languages.
- Provides better customization options and simplifies language
management.
### Challenges Encountered
- Ensuring backwards compatibility: If `languages` is empty, all
languages remain enabled.
- Handling `Set<String>` instead of `List<String>` in `LanguageService`
for optimized lookups.

# Description
Improvement in `check_language_properties.py`:
Added support for local Windows commands to check language properties
files with an updated script.
Added a new optional argument `--check-file` to specify a single file to
check, replacing the need to process all files in the directory.
Adjusted file path handling to better support Windows paths.
Update to `update-translations.yml`:
Added `workflow_dispatch` trigger to allow manual execution of the
workflow.
Documentation update in `HowToAddNewLanguage.md`:
Added instructions for running the language properties check locally on
Windows, including example commands.
These changes streamline the process of checking language properties
files and provide additional flexibility for local testing and manual
workflow triggering.
