feat(boleto): Introduce Boleto as a valid Stripe Payment Method

[julienbourdeau]

Context

We're adding support for Boleto payment method through Stripe 🇧🇷

Description

Boleto requires 2 step. First the payment is initiated on Stripe and the customer receive a barcode to go pay IRL.

This PR has very little change because most of it already works and is already tested 😅 but it requires a fair amount of manual QA.

To test the integration, you can use different email address as described in Stripe docs. By default, boleto payment are completed after 3 minutes.

TODO

• Add boleto to PaymentProviderCustomers::StripeCustomer::PAYMENT_METHODS
  • GQL: boleto is a valid payment method for a customer
  • API: boleto is a valid payment method for a customer
• When Lago creates a invoice and tries to collect it via stripe
  • Boleto is a valid payment method
  • A Lago payment.requires_action webhook is sent
  • Once the invoice is paid, Stripe sends payment_intent.succeded webhook and the invoice is marked as paid
• When using a stripe payment URL to pay an invoice
  • Boleto is a valid payment method
  • No webhook is sent for next_action since the customer is “on session”
  • Boleto is saved as a customer payment method (See feat(stripe): Save Payment Method in Customer when paying invoice with checkout url #3107)
  • Once the invoice is paid, Stripe sends payment_intent.succeded webhook and the invoice is marked as paid
• When setting up payment method (POST /customers/:id/checkout_url)
  • Boleto is a valid payment method
  • No webhook is sent for next_action because there is no payment at this stage, just setup
• When creating a PaymentRequest (POST /payment_requests)
  • If Boleto is setup, we try to collect payment with Boleto
  • A Lago payment.requires_action webhook is sent
  • No PaymentRequestMailer email is sent
