Fix: Ollama-eigenen Standardpfad statt /mnt/Data als Vorschlag anbieten

Bisher wurde in allen drei Dialogvarianten (whiptail-Yesno, whiptail-
Inputbox, CLI-Fallback) derselbe konfigurierte Pfad
(/mnt/Data/Software/ollama/models) sowohl als "Standard" beworben als
auch als vorausgefüllter Eingabewert verwendet - der tatsächliche
Ollama-Standardspeicherort kam nie zum Zug.

prompt_ollama_models_path() unterscheidet jetzt zwischen dem echten
Ollama-Standardpfad (/usr/share/ollama/.ollama/models, verwendet vom
offiziellen Installationsskript / systemd-Dienst) und dem in
OLLAMA_MODELS_DEFAULT konfigurierten Pfadvorschlag. Letzterer wird nur
noch als Vorbelegung im Eingabefeld angezeigt, nachdem der Standardpfad
explizit abgelehnt wurde.
