Get a generation

Looks up usage and billing detail for a single request by its generation id (the id field from any compatible endpoint's response). Scoped to the API key's own user — another user's generation id returns 404, never leaking their data. The response's provider field always returns the fixed value "bazaarlink", not the actual upstream provider that was routed to.
