Bug: Warning message shown prematurely during loading state

The nativeFiatSuggestion AlertCard is rendered outside the showLoadingState conditional block, so it appears even while loading shimmer cards are displayed. The message text says "Quotes shown in %1$s. More quotes may be available in: %2$s." which is misleading during loading since no quotes have actually been shown yet - only placeholder shimmer cards. The suggestion alert renders at line 249-256 regardless of whether showLoadingState is true, creating a confusing UX where users see a message about "quotes shown" alongside loading placeholders.

I think this is fine, the message is still valid even if quotes are loading. Also shimmer cards push the warning out anyway
