<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

* **New Features**
* Added automatic synchronization of language settings between the
desktop app and the system environment.
* Context menu actions (Cut, Copy, Paste) in the desktop app are now
localized according to the selected language.

* **Improvements**
* Context menu is always available with standard editing actions,
regardless of spell check settings.

* **Localization**
* Added translations for "Cut", "Copy", and "Paste" in the context menu.
