UiSlider takes v-model, min, max, step and disabled
over Core's native range input, emits numbers, and with `hold` never
rewrites a focused handle and takes the model back on blur. It is a
functional render function, so the portable style parameter rows use it
too. The Display, Radio, RTL-SDR, Cockpit, mission replay and style
parameter sliders render with it; server-rendered markup keeps their
default values.
SdrCard calls LocalSdrControls through radio store actions instead of
DOM listeners, and renders its gain options from the receiver's own
R820T gain steps with page-language labels. The display and radio
stores share one owner list (createOwners): the newest connected owner
with an action answers it.
