update: use viem for siwe

[lochie]

This PR update requires updating viem dependencies to >=2.13.3

An attempt to keep developer APIs streamlined and easy to use, we have included an easy way to include network details to your server in the same way that you set up your ConnectKit/wagmi provider.

If you have followed the ConnectKit Next.js SIWE documentation, these updates require the following changes:

First, export your ConnectKit configuration:

export const ckConfig = getDefaultConfig({ ... });

Next, in your @/utils/siweServer.ts:

import { ckConfig } from '@/components/Web3Provider';

export const siweServer = configureServerSideSIWE({
  config: {
    chains: ckConfig.chains,
    transports: ckConfig.transports,
  },
  ...
})

If you do not include this information, a default publicClient will be created attempting to use a public transport, which does not guarantee a valid communcation to the RPC url:

connectkit/packages/connectkit-next-siwe/src/configureSIWE.tsx

Lines 180 to 189 in 115cf16

	let chain = config?.chains
	? Object.values(config.chains).find((c) => c.id === parsed.chainId)
	: undefined;
	if (!chain) {
	// Try to find chain from allChains if not found in user-provided chains
	chain = Object.values(allChains).find((c) => c.id === parsed.chainId);
	}
	if (!chain) {
	throw new Error('Chain not found.');
	}

closes #323

irrelevant to SIWE update, but this required updating as useSwitchChain returns different data since the last wagmi update
