Implement Finance Dashboard and Asset Detail Screen [Flutter] #49
Description
Build the Finance dashboard screen showing total balance, percentage change, Receive/Withdraw action buttons, a "Coming soon" virtual card banner, an Assets list (Tether USD, USD Coin with price and balance), and a Transactions list with status indicators (Processing, Successful, Failed). Tapping an asset navigates to the Asset Detail screen which shows the asset balance, fiat value, Receive/Withdraw actions and a full transaction history with a "See all" link.
Acceptance Criteria:
- Finance screen displays total balance and 24h change (value + percentage)
- Receive and Withdraw buttons are tappable and navigate to correct flows
- Virtual card banner displays "Coming soon" state
- Assets section lists each asset with icon, name, price, and user balance
- Transactions list shows icon, name, date, amount, and status badge (Processing/Successful/Failed)
- "See all" link navigates to full transaction history
- Tapping an asset opens the Asset Detail screen
- Asset Detail shows per-network balance breakdown under "My USDC"
- Transaction list on Asset Detail mirrors Finance screen format
