/**
 * Prepares a set of contract calls for execution by building a user operation.
 * Returns the built user operation and a signature request that needs to be signed
 * before submitting to sendPreparedCalls.
 *
 * @param {InnerWalletApiClient<TAccount>} client - The wallet API client to use for the request
 * @param {PrepareCallsParams<TAccount>} params - Parameters for preparing calls
 * @param {Array<{to: Address, data?: Hex, value?: Hex}>} params.calls - Array of contract calls to execute
 * @param {Address} [params.from] - The address to execute the calls from (required if the client wasn't initialized with an account)
 * @param {object} [params.capabilities] - Optional capabilities to include with the request. See [API documentation](/wallets/api-reference/smart-wallets/wallet-api-endpoints/wallet-api-endpoints/wallet-prepare-calls#request.body.prepareCallsRequest.capabilities) for details.
 * @returns {Promise<PrepareCallsResult>} A Promise that resolves to the prepared calls result containing
 * the user operation data and signature request
 *
 * @example
 * ```ts
 * // Prepare a sponsored user operation call
 * const result = await client.prepareCalls({
 *   calls: [{
 *     to: "0x1234...",
 *     data: "0xabcdef...",
 *     value: "0x0"
 *   }],
 *   capabilities: {
 *     paymasterService: { policyId: "your-policy-id" }
 *   }
 * });
 * ```
