fix: theme-Auswahl + SDDM-Theme-Correctness

Drei Probleme gefixt:

1. Theme-Auswahl waehrend Install
   - apply-theme.sh zeigt jetzt alle .theme-Files via tui_choose
   - Benutzer waehlt interaktiv (gum/whiptail/basic)
   - Bei nur einem Theme: auto-select

2. SDDM wendet falsches Theme an
   - sddm.sh erzeugt /var/lib/pascal-sddm-theme/ mit user chown
   - Liest current-theme.conf + hyprpaper.conf fuer aktuelle Farben
   - Schreibt theme.conf in /usr/share/sddm/themes/pascal-hypr/
   - Config heisst jetzt 90-pascal-hypr.conf (hoehere Priority)
   - apply-theme.sh erzeugt state dir VOR theme-menu.sh --apply

3. tui_choose basic mode fix
   - ${!choice} funktioniert nicht fuer numerische Indices
   - labels+=("$@") + ${labels[$choice]} statt Positional-Params
