Subject: [PATCH] fix: score distribution chart bars + add binaryDecision
 backfill script

Chart: fixed bars not rendering by using explicit h-[160px] + min-h-0 on
the bar container so percentage-based heights resolve correctly.

Script: one-off backfill copies the custom "Move to the Next Stage?" boolean
criterion value into binaryDecision for evaluations where it's null.
Run: npx tsx scripts/backfill-binary-decision.ts
