chatgui: диагностика воспроизведения голосовых сообщений (Windows)

- sound_manager: ma_engine_init/playRawPcm логируют через DEBUG_* (qWarning/qDebug терялись в GUI-приложении без консоли); детальный результат старта PCM (rc/is_playing/cursor)
- main: ранняя инициализация лога в GUI-потоке до SoundManager::init, чтобы диагностика инициализации попала в файл
- messagedelegate: лог клика по Play/timeline (filePath/dlState/существует ли файл)
- voiceplayback: лог заголовка opus (sr/ch/frameSamples)

Попутные правки:
- u_async: фикс двойного close wakeup_pipe (eventfd/Windows)
- chat_core: NULL-guard в get_db/is_initialized
- android: sqlite открывается в utun_instance_init, cleanup stale-потока без утечки fd
- android SettingsScreen: компактная раскладка имени интерфейса
