queuePaymentCheckEmail queued the admin payment-check email with template
key 'invoice_payment_check_admin', but no such template exists — the only
one is 'invoice_payment_check' (crmEmailTemplates.js:217, seeded by
migration 116), which IS the admin "Paid / Partial / Not paid" email. The
processor does an exact template_key lookup and throws "template not
found", so every dunning admin payment-check email failed, retried to the
cap, and got stuck pending.
One-word fix: queue 'invoice_payment_check'. Unbreaks the built-in
invoice-dunning flow's email step. (Rebased onto the post-decompose
invoiceService refactor — the line now lives in invoice/payments.js.)
