feat(qbz-qt): phase 10 — Settings > Audio and Playback 1:1

settings_qt.rs controller over the shared stores (AudioSettingsState,
PlaybackPreferencesState, ui_prefs.json, qconnect_settings.db) with the
upstream cascades (dac-passthrough->skip-sink-switch, streaming-only->
gapless, backend switch resets routing) and live apply through public
player APIs (reload_settings/reinit_device/clear_audio_cache). ALSA
device regrouping (Defaults/Bit-perfect/Plugin/Other + BP badges),
searchable QbzSelect, QbzToggle/QbzSlider/SettingRow replicas, exact
row order and gating. Persistence probe verified (gapless +
streaming-quality round-trip, original values restored).
