settings: fold the frame-time refresh handlers into their row

First of the six post-construction customizations the descriptor
referee caught: the sample-gated toggle's menu-refresh handlers
lived as builder code after the add call, invisible to the index.
They are row data now - the row grammar had the slots all along -
and the intl consumer's per-file macro prelude learns the EX
variant, the same shape its generator derives from usage. Referee:
526 of 947 entries now byte-faithful from the index, action
mismatches down to two, and pointer equality on the interned tuple
proves the refresh callbacks moved intact. Both dumps and all
three displaylist passes byte-identical.

This is burn-down, not yet reduction: the five remaining
customizations gate the cut. Once the referee reads zero
mismatches, the pure-shaped build functions collapse into one
registry walker and their bodies delete - that is where the
surface and binary size come out, and it is the next thing that
lands.
