Add hu_HU for Hungarian locale (#7560)

## Description of changes

Added Hungarian locale files, and corresponding translation

For the translation I mainly relied on my native skills, double checked
my work using LLMs.

Copilot generated summary:

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.

## Picture(s) of the translation
