fix: Suchbereich deutlich sichtbarer

- Kraeftigere Fuellung (0.15-0.25 statt 0.06-0.12)
- Explizite Kanten-Polylines (width 3, 90% Opazitaet)
- Aeusserer Glow-Rahmen als zweites Rechteck
- Horizontale Schraffur-Linien fuer taktischen Look
- Groessere Eckpunkte (8px, weisser Rand)
- Label: fett, 13px, mit Hintergrund-Box
- Sichtbar bis 12.000km Entfernung
