[dev-overlay] Fix outstanding a11y issues reported by Axe (#80290) Adds labels to buttons that had no discernible text. The automated tests via `test-storybook` seem to ignore `parameters.a11y.config.rules` so we can't leverage `test-storybook` in CI. I can't even use `parameters.a11y.test`. We need `parameters.a11y.config.rules` since some of the color-contrast violations are either minor (just slightly below threshold) or false-positives either because our background is misconfigured in automated tests, or background is not detected properly.
