Rename tool_id to job_tool_id in the job branch of _format_interface_context

mypy complained about the variable being re-typed: the tool branch
assigns tool_id = _s(...) (str), and the job branch was reassigning
tool_id = ctx.get("toolId") (Any | None) in the same function scope.
Give the job variant a distinct name -- the two mean different things
anyway (tool being viewed vs. tool that produced the job).
