Vereinfache Fahrzeug-Symbolauswahl auf sechs Icons, Default suv.side

Ersetzt die zehn wählbaren Symbole durch eine kürzere, konsistentere
Auswahl (car, car.side, suv.side, truck.pickup.side, box.truck, bus)
und setzt suv.side als neuen Standard für neu angelegte Fahrzeuge.

+# Kopie von esp32_ble_solar.yaml für den Fall, dass gerade kein Votronic-
+# Regler zum Anschliessen vorhanden ist. Die `platform: votronic`-Sensoren
+# sowie UART/external_components wurden entfernt und durch Template-Sensoren
+# ersetzt, die einen plausiblen Tagesverlauf simulieren: PV-Spannung/-Strom
+# folgen einem "Sonnenstand" (ein gedachter, ca. 6 Minuten langer Tag), die
+# Batteriespannung schwankt gemütlich mit, und die Statusflags/Bitmasken
+# leiten sich aus diesen Werten ab. Die BLE-Charakteristiken funktionieren
+# dadurch exakt wie im Original - nur eben ohne angeschlossene Hardware.
+#
+# Name und Friendly Name sind bewusst auf "-sim" abgeändert, damit dieses
+# Gerät im BLE-Umfeld nicht mit einem echten VanAlign-Solar-Gerät kollidiert.
+#
+# Für Debug-Zwecke läuft WLAN mit und die Werte werden zusätzlich auf dem
+# eingebauten Webserver (Port 80) angezeigt; WLAN-Zugangsdaten liegen in
+# secrets.yaml (lokal anzulegen, ist per .gitignore ausgeschlossen). Alle
+# simulierten Werte aktualisieren sich höchstens jede Sekunde, damit sich
+# Änderungen beim Debuggen zügig zeigen.
+#
+# Sobald wieder ein echter Votronic-Regler verfügbar ist, einfach
+# esp32_ble_solar.yaml weiterverwenden - diese Datei ist nur zum Testen der
+# App/BLE-Anbindung.
