Regression in OpenTodoList 3.50.0's localization on macOS

First of all, a happy new year 2026 and big 'thank you' for releasing OpenTodoList 3.50.0!

Here's a follow-up issue to #650 (closed) : I'm using the new version on macOS Sequoia 15.7.3 (Intel) and I've noticed there seems to be a regression in the application's localization again: No matter if I select 'System Language' or 'French' or 'German' for the application language, the GUI language remains English, also after an app relaunch.
