Geozone-aware risk assessments

Includes active geozones in the five-level Risk Assessment instead of showing a contradictory very-low result.
Treats prohibited zones as critical, authorization zones as high, warning zones as elevated, and informational zones as low risk.
Shows the geozone warning directly below the score while retaining the detailed zone list and final stop warning.
Keeps a visible start-position marker and opens Risk Assessment maps at a wider zoom level.
Points France to the incoming cartes.gouv.fr service, keeps Belgium on the official Droneguide map, and prepares the official Netherlands ED-269 direct download for controlled synchronization.
