feat: sdk connector interface improvements, and more

[JackHamer09]

Description

SDK quality of life and typesafety improvements, as well as bug fixes for constraint abi indexes.

• New zksyncSsoConnector interface:

import { zksyncSsoConnector, callPolicy } from "zksync-sso/connector";

zksyncSsoConnector({
  session: {
    expiry: "1 day", // human readable time

    contractCalls: [
      callPolicy({ // new helper function, provides type safety
        address: "0x...",
        abi: erc20Abi, // now have to provide abi
        functionName: "transfer", // typesafe function name
        constraints: [
          {
            index: 0,
            value: "0x6cC8cf7f6b488C58AA909B77E6e65c631c204784", // typesafe value, converted to abi bytes32 on SDK side
          },
          {
            index: 1,
            limit: {
              limit: 1n,
              period: "1 hour", // human readable time
            },
          },
        ],
      }),
    ],
  },
});

• Added few additional wagmi methods, e.g. getConnectedSsoClient. It provides a way to get properly typed ZKsync SSO client, so that developers can access things like session key and other available parameters and methods.
