Fourth (and final /master tests) pass. This is for de- mocking the recovery tests to use real SDK functions.

Updated musigRecovery.test.ts, nonRecovery.test.ts, recoveryWallet.test.ts, recoveryConsolidationsWallet.test.ts, recoveryWalletMpcV2.test.ts

• Dropped middleware/coin stubs with same approach as earlier de- mocked tests. Unlike wallet ops like sendMany, recovery endpoints take keys in the request body and don’t fetch wallets from BitGo, so the real expressApp(config) app setup works as-is without that stubbing now. We nock external chain APIs (Blockchair, Etherscan, TronGrid, Solana/SUI RPC) instead of stubbing coin.recover / recoverConsolidations.
• Changed beforeEach -> before since app setup no longer depends on sinon stubs, so we create the app once and reset nocks/stubs in afterEach.
• TRX/SOL/SUI keys and addresses in recoveryConsolidationsWallet.test.ts come verbatim from the SDK’s test fixtures so derivation and tx building match what the real SDK expects. AWM signing is still nocked.
• Still stubbing Trx.prototype.recoverConsolidations in the “unexpected result structure” test as it's the only way to hit that error path since the real SDK always returns { transactions } or { txRequests }.
• AWM nocks use body matchers where the SDK builds more complex dynamic payloads.
