Card thumbnails lived in ComfyUI's temp folder, which ComfyUI empties on
every start, so each first visit after a restart remade them all. They now
live in <user>/anomalous/cache/card_thumbnails (still capped at 256 MB).
Listing a model type queues the missing ones for one background thread;
the first screen of cards loads before the rest. A video cover gets a
first-frame poster (PyAV) and fetches nothing until it plays; hover-play
is now the default, as the setting already recommended.
The gear opens a settings page instead of a pop-up with a dialog inside:
look and language, model cards and memory with the thumbnail cache (size,
empty), folders, workflow fingerprints, opening mode and window, help.
Display preferences live behind owner.displayPrefs. Also removes a dead
overlay rule that shared the new page's id.
