Fix USDT display in mobile wallet (show USDT instead of wUSDT)

Browse Source 
User experience improvement:
- Display "USDT" (Tether USD) in UI instead of "wUSDT"
- Backend still uses wUSDT (asset ID 2) for blockchain transactions
- Similar to trcUSDT on Tron - users see USDT, wrapped token works behind the scenes
- Updated all references: symbol, balance keys, transaction logic

This maintains the wrapped token architecture while providing familiar USDT branding.
