What happens when a payment link is used

At a high level, when a payment link is used:

1. Loop creates a customer record (an agreement) and emits the AgreementSignedUp webhooks
2. Loop creates an invoice based on the billing settings associated with the product and/or subscription and emits the TransferCreated webhook.
3. Loop charges the customer onchain based on the bill details and emits the TransferProcessed webhook.
4. (Subscriptions only) Loop creates the next invoice and emits the TransferCreated webhook.

It could take a few minutes for a transaction to confirm onchain due to chain confirmation times.
