Policy version history

Append-only policy revisions. Every change (including edits to limits and approvers) creates a version with a snapshot of the decision-making part: effect, condition, approval, limits, approvers.

reason: created on creation; updated on edit; backfill means the version was assembled by migration 0041 from the current state and is NOT guaranteed to match the one that made older decisions.

A decision references its version via the decisionPolicyVersionId field; for decisions older than Phase 4, it's null, since the version is unknown.
