30. Balance card

[Miracle656]

Goal: Show the user their primary balance the moment they open the app — native XLM
plus its fiat value fetched from the Lens price oracle. This is the most-looked-at element
in the product, so it must load quickly and degrade gracefully when the price feed is
unavailable.
Create: frontend/mobile/components/BalanceCard.tsx, frontend/mobile/lib/fetchPrice.ts.
Port/reference: frontend/wallet/lib/fetchPrice.ts (fetchPrices, Lens NEXT_PUBLIC_LENS_URL), balance query in dashboard/page.tsx.
Acceptance: shows XLM balance + USD via Lens; handles price-fetch failure.

Good day maintainer,I would like to apply for this issue. I can create frontend/mobile/components/BalanceCard.tsx and frontend/mobile/lib/fetchPrice.ts by porting the web's balance query and Lens oracle price-fetching logic. This will deliver a fast-loading dashboard component that cleanly handles fiat conversions while degrading gracefully to token-only amounts if the network or price feed is down. I am ready to open a fast, high-quality Pull Request today.
