Refactor workflow-logic-function-interaction (#17699)

# Refactor workflow–logic function interaction

## Why

Workflow code steps and standalone logic functions shared the same build
layer and DB layer, which blurred two use cases: code steps belong to a
workflow version; standalone functions are deployable units. That made
workflow code steps harder to own and evolve.

## Goal

Treat code steps as **workflow-owned**: build and run them in workflow
context, and expose workflow-scoped APIs so the editor can load, test,
and save code step source without going through the generic
logic-function layer.
