* linux(i18n): add Turkish translations
- Add Qt Linguist translation infrastructure to CMakeLists.txt
- Wrap UI strings with qsTr() in Main.qml
- Wrap menu strings with tr() in trayiconmanager.cpp
- Add QTranslator loader in main.cpp for automatic locale detection
- Create Turkish translation file (librepods_tr.ts)
Translations include:
- Main window: connection status, noise control modes, settings
- Tray menu: all menu items and tooltips
- System notifications
* fix: allocate QTranslator on heap to ensure lifetime
* docs: add troubleshooting section for media controls not working
* always use white text for the battery percentage in the system tray icon which matches what other applications like Bluetooth battery indicators do in Plasma
* init librepods asset
* remove update script for librepods
