Introduce the Settings page, reachable from the Discover gear and the
header menu. Two sub-sections backed by the existing UI-agnostic stores.
- Audio panel: backend, output device and sample-rate dropdowns;
toggles for exclusive mode, DAC passthrough, PipeWire force
bit-perfect, gapless, normalization and quality fallback
- Playback panel: autoplay mode, show context icon, remember session
and resume position
- settings.rs controller owns AudioSettingsStore + PlaybackPreferencesStore
at the shared global path; persists changes and applies audio ones to
the live Player (reload_settings, plus reinit_device for routing-
critical changes); a backend switch re-enumerates output devices
- QbzToggle (switch) and QbzSelect (PopupWindow dropdown) primitives,
SettingRow layout helper, chevron-down icon
- SettingsState global, ContentView::settings, settings-bool /
settings-select callbacks wired through the shell

The header is now three equal sections — navigation tabs (left), the
search field (center, so it lands at the window center), and the user
element (right) — fixing the tabs stretching to full width under the
search field.
- Nav tabs regain Lucide icons (compass, library, hard-drive,
cassette-tape) and use a 12px label.
- The user element uses a hamburger icon instead of the QBZ logo, which
aliased badly as a scaled PNG.
- Responsive: below 1140px the tabs drop their icons; below 960px the
search field narrows to 70%.

Adds 28 Lucide icons (the same set the QBZ Svelte app uses) as SVGs
under ui/assets/icons/, plus a QbzIcon primitive — an Image wrapper that
applies `colorize` so a monochrome SVG renders in any theme color.
