Description

This PR adds the download data UI for the Scribe-Conjugate app.

Files changed:

• app/src/main/java/be/scri/ui/screens/download/ConjugateDownloadDataScreen.kt (new) - A new screen that displays all 8 supported languages (English, French, German, Italian, Portuguese, Russian, Spanish, Swedish) sorted alphabetically. Unlike the keyboard app's download screen which only shows installed keyboards, this screen always shows all languages. It reuses shared components (LanguageItemComp, CircleClickableItemComp, SwitchableItemComp) and shared data classes (DownloadActions, CheckUpdateActions, LanguageItem) from the keyboard app. There is no empty state and no translation source language confirmation dialog, as these are keyboard-specific features.
• app/src/main/java/be/scri/App.kt - Added a new "conjugate_download_data" navigation route wired to ConjugateDownloadDataScreen, and updated ConjugateScreen's onNavigateToDownloadData to use this route instead of the keyboard app's "download_data" route.
