Create Invoice POST

Create a new invoice for a clinic. Lab-only. Automatically generates an invoice number; issued invoices create the corresponding account transaction while drafts remain ledger-neutral.

Email Invoice POST

Send an invoice via email to the clinic's billing or primary email address. Lab-only. Also emits an in-app notification to clinic owners.
