feat(display): render the style parameters from the display store

VisualSettings publishes the active style's parameter rows to the display
store, and the Display panel renders them with the shared row component;
a moved slider goes back through the store's setStyleParameter action.
The readout snaps a value to its step as the browser does, half-steps up
and an off-grid maximum down. A preset that resets the shown style's
uniforms republishes its rows, input for another style's parameters is
ignored, and a stopped owner takes its rows with it unless a newer owner
has published since. createStyleParameters is deprecated and builds its
rows the same way.
