Fix duplicate prompts after whiptail menu selection

Applied WHIPTAIL_USED flag check to all 25 service prompts that appear
after the whiptail menu to prevent services from being prompted
individually when they weren't selected in the checkbox menu.

This fixes the issue where services like AudioBookshelf were being
prompted even when not selected in whiptail.

Services fixed:
- AudioBookshelf, Emby, ARM, FileBrowser, Magic Mirror
- ActualBudget, Keycloak, Caddy, fail2ban
- Lyrion Music Server, Mealie, Minecraft, Jellyfin, Frigate
- ddclient, ntfy, Uptime Kuma, wg-easy
- Traccar, Portainer, MeshCentral Server
- FindMyDevice, Frigate-Notify, Watchtower

Pattern applied:
  if [ "$WHIPTAIL_USED" != true ] && [ -z "$INSTALL_SERVICE" ]; then
      # Show prompt
  fi

This ensures prompts only appear when whiptail was not used OR
the service variable is not yet set.
