Keep a compact header navigation bar visible on the About page so users
can return to station browsing. Make the sidebar logo navigate home and
add World to the compact header navigation.
Use consistent German labels (Info, Angaben, Nachrichten, Pausieren)
while keeping established tech terms like Votes, Bitrate, and Stream.
Restore C++ string translations for tray, backend errors, and notifications.
Replace the modal About dialog with an embedded About page and introduce
a three-pane desktop layout: persistent sidebar navigation, flat station
list, right-side details panel, and compact player bar.
Load the GPLv3 license text from C++ and expose it to QML as context
data. Normalize i18n source strings to English, complete German and
Russian translations (133 strings each), and centralize page navigation
helpers in Main.qml. Simplify compact HeaderNavigation and extend
.gitignore for local build artifacts.
