In the desktop app we use the webview's native zoom, which scales every
pixel uniformly (exactly like browser zoom) — the only mechanism that also
scales the px-based icons and inline sizes scattered through the UI. The
webview resets to 100% on each launch, so callers re-apply the persisted
value on boot. In the browser dev server there is no Tauri webview, so we
fall back to the CSS zoom property. Only one mechanism is ever active, so
the two never compound.
Apply the zoom factor to the whole interface.
