Add "Disconnect wallet" button (clears stuck WC session / switch wallets)

A stuck WalletConnect request or wrong-wallet choice could trap testers. New
IAPWallet.disconnect() drops the WC session, forgets the chosen provider, and
clears WC localStorage so the next connect re-offers the picker. Surfaced as a
"Disconnect wallet" button on the Wallet pane.
