Multiple currency support for product creation and accepting payments

Business users will now be able to create products in their preferred choice of currency and accept payments
This means that the business country would no longer define the currency of the products, invoices, or Text2Pay links. Users will be able to select any currency while creating the same
This solves a major point of creating separate products targeted toward specific geographies or sending invoices to customers in different countries
This covers support in creating preferred currency products, sending one-time or recurring invoices in any currency, sending a Tex2Pay link as per the contact's country and currency, and charging a card while on the contacts list page.
