Refactor: Overpass nur via VLM, Panel ersetzt rechte Sidebar

- Overpass-Toggle aus Layer-Panel entfernt (kein Standalone-Modus)
- Overpass-Panel und UI-Script entfernt
- VLM-Panel nach rechts verschoben, ersetzt Sidebar wenn aktiv
- Sidebar wird automatisch ein-/ausgeblendet bei VLM Toggle
- VLM ruft Overpass API direkt auf (kein Umweg ueber OverpassUI)
- Ergebnis-Zaehler im VLM-Panel statt separatem Overpass-Panel
