Use the `oscar-billing-status-extension` on this invoice to preserve the 10-code Oscar enum.

Oscar → FHIR status mapping (see oscar-to-fhir feature docs):

| Oscar | FHIR Invoice.status | Notes |
|---|---|---|
| O (Bill OHIP) | `issued` | |
| P (Bill Patient) | `issued` | + `payProgram` extension |
| W (Bill WCB) | `issued` | + `payProgram=WCB` |
| B (Submitted OHIP) | `issued` | awaiting adjudication |
| X (Bad Debt) | `cancelled` | + `oscarBillingStatus=X` |
| H (Capitated) | `balanced` | + `shadowBill=true` |
| I (Bonus Codes) | `issued` | + `oscarBillingStatus=I` |
| S (Settled) | `balanced` | |
| D (Deleted) | `cancelled` | |
| N (Do Not Bill) | `entered-in-error` | |

Current `InvoiceConverter` (`InvoiceConverter.java:510-540`) emits `InvoiceStatus.NULL`
(absent status) for H and I, and incorrectly groups X with ISSUED. MTG-074 must remap H/I/X
to the target values in the table above."/>
