style(admin-web): apply blurred-backdrop cover treatment to KOL cards

Switch KOL package, template, and workspace card covers from object-fit
cover to a blurred backdrop with a contained foreground image so non-16:9
artwork no longer crops awkwardly. Also restyle the package detail back
button, swap the generate-button copy for the canonical key, and rename
"prompts" counts to "refined templates" in i18n.
