feat(system): Appearance defaults used by Images and the viewer

System > Appearance is the concept's Browsing & display surface on real
values: the browser rows edit this browser's display defaults through the
shared gallerySettings object, and Open from ComfyUI and the node search
auto-hide save to the server settings with their revision. A new Images
visit starts from the default layout and size (the current view and saved
views keep theirs); metadata off waits for Load metadata; cache off re-reads
the shown file; paths off hides the Path row; the viewer reads the video
defaults. D97 adds card details, collapsed viewer details and Reset display
defaults; storage refused says Saved for this tab only.
