fix(map): Kartenlegende theme-aware (closes #5)

- style.css: .legend nutzt CSS-Variablen (--tblr-bg-surface, --tblr-border-color,
  --tblr-body-color) statt hardcodierter Hex-Farben
- map.js: legendDiv-Referenz, updateLegendTheme() setzt Inline-Styles;
  wird beim onAdd (Init) und im themechange-Listener aufgerufen

 # Changelog
 
+## [0.08.23] - 2026-02-20
+
+### Fixed
+- **Karte: Legende theme-aware** (closes #5): `.legend` nutzt jetzt
+  `var(--tblr-bg-surface/border-color/body-color)` statt hardcodierter Farben.
+  `map.js` speichert die Legende als `legendDiv` und aktualisiert per
+  `updateLegendTheme()` Inline-Styles beim Init und bei jedem `themechange`-Event –
+  zuverlässig auch im Leaflet-Control-Kontext.
