Feat: Bestätigungsabfrage vor Ollama-Speicherort-Dialog hinzufügen

prompt_ollama_models_path() fragt jetzt zuerst per Ja/Nein, ob der
konfigurierte Standard-Speicherort (OLLAMA_MODELS_DEFAULT) verwendet werden
soll - analog zum bestehenden Muster in tui_prompt_target_user(). Nur bei
"Eigenen Pfad angeben" erscheint der Eingabedialog, vorbelegt mit genau
diesem Standardpfad. Gilt für whiptail-TUI und den CLI-Fallback gleichermaßen.
