SliderFieldWidget class
slider. A Material Slider when SliderComponent.multiple is false, a
RangeSlider when true — the value is a number or a two-element List
respectively, round-tripped through the ordinary form paths. Bounds and
divisions come from the node's config; the enforceable half of the same
declaration rides the ordinary rules block into the shared validator,
so there is no slider-specific validation here.
A range slider with no array default publishes multiple: false on
/schema (the documented server weakness — isMultiple() reads the raw
state at walk time) and /state may re-answer true. Nothing here treats
either answer as more than a rendering hint: the control renders from the
node it is given, a value shaped for the OTHER mode reads as unset rather
than crashing, and a submission is never blocked on the client hint.
