Give workflow node tools the owner's toolset whoever runs the workflow

A node's tools resolved as the person running the workflow, so a teammate
or public-link user lost every owner tool they could not use themselves.
They now resolve as the workflow owner, then as the editor who attached
them, like an agent's own tools. The runner stays the invoker, so a
member-mode connection still uses their own account.
