windkarte: Rechtskräftig default hidden, remove Entwurf-2-voraussichtlich, 2km/5km rings on by default

- Hide status badge for rechtskraeftig in WindAreaPanel
- Default hiddenStatuses=["rechtskraeftig"] so polygons start hidden
- Fix: call restyleAll after geojsonLayer init so initial hidden state applies
- Default hiddenRings=[] so 2km+5km buffer rings show on selection
- Remove entwurf_2_voraussichtlich from legend
- Lower maxZoom 12→11 for more context on feature select
