collab: Add has_overdue_invoices to billing_customers (#24239)

This PR adds a new `has_overdue_invoices` field to the
`billing_customers` table.

This will be used to statefully track whether a customer has overdue
invoices, and also to reset it when the invoices are paid.

We will set this field to `true` when a subscription is canceled with
the reason `payment_failed`.

Release Notes:

- N/A
