+[1.1.176] – 2025-05-26
+🐞 Fixed
+Problem behoben, dass das Modal „POI hinzufügen“ nach erfolgreichem Submit nicht geschlossen wurde und die Meldung „Wird hinzugefügt…“ dauerhaft sichtbar blieb.
+
+Ursache: Die Service-Datei addPoiService.js verwendete die falsche URL /addLocation statt /addPoi.
+
+Die unwrap()-Verwendung im AddPOIModal.js wurde beibehalten und korrekt abgeschlossen.
+
+✅ Clean
+resetAddPoiStatus() wird jetzt direkt nach onClose() dispatcht, um Status in Redux auf idle zurückzusetzen.
+
+Ladeindikator „Wird hinzugefügt...“ wird zuverlässig entfernt.
+
+Fehleranzeige funktioniert weiterhin über Redux (status === "failed" und error).
+
+🧠 Architektur
+Vollständige Redux-Anbindung des Modals über addPoiSlice, addPoiThunk, addPoiService und addPoi.js.
+
+Thunk-Erfolg löst incrementTrigger() aus und synchronisiert die Marker auf der Karte durch erneutes Laden via fetchPoiMarkersThunk().
+
+🔧 Version
+📦 Version erhöht auf 1.1.176
