test(ui): exclude producer tag story from visual regression

The new Settings/ProducerTag story added 2 new visual snapshots, which fails
the Visual Review check until a human approves them. It's a manual demo/record
surface that doesn't need a signed baseline, so tag it "test-skip" — the
Storybook test-runner skips it from snapshot capture. The story stays visible
in Storybook for manual use.
