/**
* Sign a transaction for a specific TSS wallet
*
* This endpoint signs a transaction for a specific TSS wallet identified by coin type and wallet ID.
* The request body is passed to wallet.signTransaction() and varies by coin and wallet type.
*
* Common fields for TSS wallets include:
* - txPrebuild: Contains transaction data like txHex, txBase64, or txRequestId
* - walletPassphrase: Passphrase for TSS wallets (required for TSS signing)
* - txRequestId: Transaction request ID for TSS wallets (can be in body or txPrebuild)
* - apiVersion: 'lite' or 'full' for TSS transaction requests
* - multisigTypeVersion: 'MPCv2' for MPCv2 wallets
* - isLastSignature: Whether this is the last signature in a multi-sig tx
* - pubs: Public keys for multi-signature transactions
* - gasLimit: Gas limit for ETH transactions
* - gasPrice: Gas price for ETH transactions
* - expireTime: Transaction expiration time
* - sequenceId: Sequence ID for transactions
* - isEvmBasedCrossChainRecovery: For EVM cross-chain recovery
* Sign transactions for MPC wallets. If using external-signer mode, you must maintain your keys, in the clear, on a separate Express server - BitGo doesn't decrypt your private MPC key shares.
*
* @tag express
* @operationId express.v2.wallet.signtxtss
