WIP for a POC integrating eliza with Trustless Work

/**
 * Changes the flag property of a specific milestone in an escrow to approve that milestone.

 * @param contractId - The ID (address) identifying the escrow contract.
 * @param milestoneIndex - The index of the milestone within the escrow.
 * @param newFlag - The new value for the flag property of the milestone.
 * @param client - The address of the client who approves the milestone.
 * @returns The updated escrow object.
 * @throws Error if the escrow or milestone is not found.

  // Optionally, you can add a check for client authorization here if needed
  // Example:
  // if (escrow.client !== client) {
  //   throw new Error(`Client ${client} is not authorized to approve milestones for escrow ${contractId}`);
  // }

  // Update the milestone's flag to the new value
  milestone.flag = newFlag;
