fix(doctor-report): name a managed record by its display name

The report cover, the PDF author field, the FHIR Patient and the share
page printed `fullName ?? username`, and the collector never read the
display name. A managed record has no way to get a full name, so its
generated `managed-<hex>` login landed on every clinical document made
for it; an own account printed the login instead of its display name.

The collector now resolves the name once (`patientName()`: full name,
display name, login, never a managed record's generated handle) and the
five readers print that one field. `patient.username` and
`patient.fullName` leave the report payload; nothing else read them.
