Advertising totem can be added in things overlay but is not displayed

Likely affects other things without dedicated icon

( I plan to look into this, I will assign myself once actual work will start - but feel free to take over this)

Hints: Check if the icon is actually present. If it is not present, check what the download and convert preset icons task logged, maybe the icon is either missing or uses some svg features that the convert-task does not support. In general, maybe there should be a fallback icon (a dot) for such cases in general.
