Context

MoneyHash is a leading payment infrastructure software in Africa and the Middle East. Our biggest features are providing a superior payment orchestration for many payment providers in the region, smart payment routing among other features.

We have common customers, and it's a needed feature to have MoneyHash integrated into Lago.

This PR integrates MoneyHash as a payment provider for Lago's customers.

Description

This PR implements the following changes

• When a new customer is created in Lago and the "sync with provider" checkbox is checked, a new customer is also created in MoneyHash.
• Create a payment URL for invoices, allowing customers to pay their invoices via MoneyHash
• Create Payment Requests that are processed using the customer's payment method.
• Webhook Handling
  • Transaction Webhooks
    • On the "transaction.purchase.successful" callback, the invoice/payment status is set to "Succeeded."
    • On the "transaction.purchase.failed" callback, the invoice/payment status is set to "Failed."
  • Intent Webhooks
    • On the "intent.time_expired" callback, the invoice/payment status is set to "Failed."
  • Card Token Webhooks
    • On the "card_token.created" and "card_token.updated" callbacks, the customer’s payment method ID is added or updated.
    • On the "card_token.deleted" callback, the customer’s payment method ID is removed.

List any dependencies that are required.
