feat(smzdm): require 1:1 cover and surface image fetch failure prompt

Add SMZDM to the cover-required platform list on both client and server,
register a 800x800 native cover spec in the admin cover catalog, and
normalize the desktop-client `smzdm_image_fetch_failed` adapter error to a
user-friendly Chinese prompt across the publisher error pipeline.
