The earlier change only relabeled is_monthly_draft rows. But a per-event
invoice created from hours is status 'scheduled' with scheduled_send_at = NULL
and is_monthly_draft = false — it never auto-ships (the scheduler only picks
rows with scheduled_send_at <= now), yet it still read "Scheduled" on the
customer panel + lists.
Add a shared isDraftInvoice() helper (scheduled && no send date, or a
monthly/manual accumulator) and use it for the badge in the Bills list, the
invoice detail header, and the customer profile's invoice panel. A scheduled
invoice WITH a future send date keeps "Scheduled".
