Turns the record that changed into the action's Scope parameter.
Evaluated per-invocation as an EntityActionParam of ValueType Script, because the whole point
of an on-change trigger is that the record differs every time — a Static value would pin the
binding to whichever record happened to be open when it was configured.
ToConcatenatedString() and not ToString(): RecordRef.RecordID is documented as the primary
key "serialized to a composite-key-safe string", which is that format. ToString() is a display
format and would silently fail to resolve a composite key.
