Move marketplace reads into UsernameMarketplaceViewModel.
loadState() and loadHistory() call the marketplace service from the SwiftUI MarketplaceNameDetailSheet. Move these reads and their loading state into UsernameMarketplaceViewModel. Let the view render published state and call a ViewModel API.
As per coding guidelines, “Concretely banned inside SwiftUI View structs: FFI/SDK calls … Those live in the ViewModel or a service.”

Opening a username from My Names could leave the detail sheet showing only a spinner for roughly 90 seconds. The sheet waited for both the live-name request and the supplementary trade-history request in sequence before rendering any useful content.
