fix(TMCU-538): update error state icon to new no-connection illustration

Replace the flat IconName.WifiOff design system icon in the shared
ErrorState component with themed PNG illustrations matching the new
design from Vinay. Uses useAssetFromTheme to switch between light
and dark variants, following the same pattern as CollectiblesEmptyState.

Affects all homepage sections that show error states: Tokens,
Predictions, Perpetuals, and DeFi.
