Hold the navigation bar item to its own label and state-layer tokens
NavigationBarTokens names one label font for both icon positions, label-medium; the horizontal layout had taken label-large from the rail's item, a different component with a token of its own. And the item's state layer washed in on-surface over a secondary-container pill, where the only state-layer tokens M3 states for a navigation item — the rail's, which the rail already follows — are on-secondary-container for all six states. Plan: docs/plans/material-3-alignment.md, step 21 (navigation N-08, N-19).
