Emit one `MedicationAdministration` per intake the user actually
actioned — `completed` for a taken dose (`effectiveDateTime = takenAt`),
`not-done` for an explicit skip (`effectiveDateTime = scheduledFor`).
Pending / missed slots and soft-deleted tombstones are never exported,
so the record only asserts administrations that happened.
Each administration reuses the statement's ATC/RxNorm + text concept,
so it is self-describing without a cross-resource reference. A `dosage`
is emitted only when a structured dose Quantity is available (resolved
from the dose-change history in effect at the administration instant) —
a dosage carrying only `.text` would violate the R4 dose-or-rate
invariant. Route + injection site ride along as text-only concepts. The
administrations are referenced from the existing Medications section, so
the document's two-section graph is preserved.
`FhirMedicationAdministration` is new; `FhirDosage` gains `dose`,
`route`, and `site`. The source rows come from the same aggregator the
PDF consumes, keeping FHIR and PDF aligned by construction.
