Integration of AfP Transactions component

[gcatanese]

Integrates the AfP Transactions component to display the transactions performed by the Account Holder.

The PR implements the following:

• invoke the Session Authentication API to obtain the session token
• render AfP Transactions web component on the UI
• add an example of custom CSS styles

The previous implementation of the screen is still available (TransactionsCustomView.js) to provide an example on how to build a custom view using the API-only approach.
