feat(decodes): NEW STATE — badge and filter

The WAS gap made visible: a worked-states set joins the cluster status cache
(distinct states over the three US entities), the status entries carry a
NewState flag wherever the state resolves (log county first, ULS licence
second), and the decode panel gains the badge in its status column plus the
filter chip alongside NEW/BAND/MODE/GRID. Colour from the shared marker
palette, so the cluster can adopt it later without a second hue.
