[GH] (fluss/feature/update-if-changed-merge-engine): Workflow run "Client Integration" failed!

[server] Support update_if_changed merge engine for primary-key tables

Introduce an UPDATE_IF_CHANGED merge engine that keeps last-row upsert
semantics but suppresses value-identical writes: when an incoming row is
logically equal to the stored row, the write is a no-op and no changelog is
emitted; when a field differs, the row is updated normally. Delete, partial
update and schema evolution are supported.

Equality is by logical field values (SQL null semantics, binary compared by
content, older-schema rows aligned to the latest schema).

Closes #4343
