This pull request introduces Hungarian language support to the
application by adding translations and updating the locale
configurations. The most important changes include the addition of
Hungarian translations in the `.po` file and registering the new locale
in the application's supported locales.
### Hungarian Language Support:
* Added Hungarian translations for various UI elements and messages in
the `po/hu_HU.UTF-8.po` file. This includes translations for prompts,
dialogs, menus, and other interface components.
* Updated the supported locales list in `src/os/i18n.zig` to include
`hu_HU.UTF-8`, enabling Hungarian as an available language option.
