feat: generic tx toaster

[sinzii]

This work add a generic abstraction for tx toaster. The txToaster core logic now will be move to typink package. So dapp can import and use.

We also implement adapters for popular toaster libraries (sonnet, react-toastify and react-hot-toast) so we can set this up easily via the setupTxToaster method with other customizations.

E.g:

import { SonnerAdapter, setupTxToaster, ReactToastifyAdapter, ReactHotToastAdapter } from 'typink';
import { toast } from 'sonner';

setupTxToaster({
  adapter: new SonnerAdapter(toast), // ReactToastifyAdapter, ReactHotToastAdapter
  initialMessage: 'Signing Transaction...',
  autoCloseDelay: 5000, // ms,
  messages: { // customize the toast inner message as needed
     inProgress: 'Transaction In Progress',
     successful: 'Transaction Successful',
     failed: 'Transaction Failed',
  }
});

The ToastAdapter interface is keep minimal so devs can implement new different implement for other toast libraries as needed.

Merging this for now, we'll also need to update the templates to use this new txToaster logic as well but should be done in a different PR.
