Fix: DF Dash taint on secretRect icon borders (defensive + missing buff)

DF_DASH lays its dashes out from the border frame's width/height, but on
the 12.1 container icons that rect is SECRET — reading GetWidth() taints
and throws (spammed once per frame via the anim driver). The knownWidth/
knownHeight feed already exists for exactly this (AD placed borders use
it, which is why the AD frame border was fine); the defensive slot and
missing-buff badge just weren't passing it. Feed the configured slot /
badge size so the dash math uses it instead of the secret rect. Only
DF_DASH reads the frame size; the overlay effects anchor relatively.
