Switch the choropleth from heartbeat-red to the greyscale ramp

Driver ruling: "instead of the red, we need to use the grey scale from grey
to black." The greyscale preset was built earlier at his request as a
swappable alternative; this is him taking the swap.

One config key moves both the choropleth and its legend together, which is
why it was built as config rather than scattered hex. Ramp is
#e8e8e8 / #a9a9a9 / #6f6f6f / #3a3a3a / #060606.

Verified in the shipped bundle: colorRamp "greyscale", the five stops
present, sfc-parse passes.

Worth knowing for the follow-up: the colour research measured the ramp
change as roughly neutral for pin visibility (worst case 1.96 greyscale vs
1.84 red). The real fix for pin contrast is the lightness-conditional stroke
-- dark ring under a light pin, white under a dark one -- which lifts the
worst case to 4.51 and works on either ramp. Not done here; that is its own
change.
