We want to verify the txHex with params provided by client before signing

[Copilot]

Pull Request Overview

This PR adds validation for unsigned txHex by introducing a new txParams field and corresponding verification steps before signing transactions. Key changes include:

• Passing txParams from txPrebuild to the signTxRequest call.
• Updating the TSS ECDSA utilities (both MPCv2 and classic) to verify transactions using the provided txParams.
• Adjusting test cases and related type definitions to support these new validation steps.

• [nitpick] Confirm that the error message for a recipient address mismatch is consistent across all validation cases.

.should.be.rejectedWith('destination address does not match with the recipient address');

modules/bitgo/test/v2/unit/internal/tssUtils/ecdsa.ts:974

• [nitpick] Ensure that the error message for an amount mismatch remains consistent with other areas of the codebase that implement similar validations.

.should.be.rejectedWith('the transaction amount in txPrebuild does not match the value given by client');

Review the allowed transaction types here since 'transferToken' was replaced with 'transfer'. Ensure this change is intentional and that it aligns with the client specifications.
