Changes Made

• Added and exported resolveSupportedNetworkId in frontend/src/components/wallet/WalletMismatchBanner.tsx to map wallet-reported network labels/passphrases to supported app NetworkId values (mainnet, testnet, futurenet, sandbox).
• Rendered both the wallet's reported network name (data-testid="wallet-network-badge") and the app's active network name (data-testid="app-network-badge") in bold <strong> badge elements inside the role="alert" banner.
• Added the "Switch App to Wallet Network" button that calls setNetworkId(targetNetworkId) when supported (and disables gracefully for unrecognized custom networks).
• Added the "Re-check Connection" button that re-queries the connected wallet via connect(selectedWalletId ?? session.walletId) and dismisses the banner once the mismatch is resolved.
• Added unit tests in frontend/src/components/wallet/WalletMismatchBanner.test.tsx.
