feat(ui): add AreaDropdown and exclusive toggle with layers panel

New AreaDropdown component for quick station selection (filters by allowed systems, ESC to close)
MapComponent: toggle AreaDropdown via MapMarkerIcon; auto-hide MapLayersControlPanel when dropdown is open and vice versa
fix(alarms): hasActiveAlarm now checks Statis[].Alarm for both array and object shapes
fix(panel): Kabelstrecken now auto-enables TALAS (system-1) when turned on; keeps behavior to disable polylines when TALAS is unchecked; persists visibility to localStorage and emits visibilityChanged
Minor: imports, state wiring, and render guards updated
Affected files:

MapComponent.js
MapLayersControlPanel.js
AreaDropdown.js (new)
