### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #xxx
Problem Summary:
Row-binlog and table-stream paths derived current, before-image, and
system-column positions independently in BE from column names and physical
layout. This coupled reads and writes to layout details and caused key-only
tables requesting historical values to select plain derivation. Compute stable
mapping identifiers in FE, downlink them through Thrift and protobuf, resolve
ordinals once in BE, and consume explicit CID mappings in write derivation.
Preserve mappings only while pending transactions may recover, then clear them
before local or Cloud rowsets become visible.
