A medication's dose is stored as free text the wizard composes from an
amount and a unit token ("1 pieces", "2 tablets"), and the card rendered
that token verbatim glued onto the name — so the unit showed in English
on every locale and the title read "Test ABC 1 pieces".
Translate the dose at display time: a formatDose helper splits the stored
string and runs a known unit token through the existing unit messages, so
"1 pieces" reads "1 Stück" / "1 piece(s)" per locale while a custom
free-text dose passes through untouched. The card header now carries the
name alone on its title line with the dose on a muted line beneath it,
above the category badge; the detail view, table and intake dialogs
localise the same way. Vorsorge and lab rows pass an empty dose so they
render no extra line.

/**
|
|
* Display-time dose formatter.
|
|
*
|
|
* The wizard composes `Medication.dose` as a free-text string
|
|
* `"{amount} {unitKey}"` storing the RAW unit key (e.g. "1 pieces",
|
|
* "5 mg"). Rendered verbatim that leaks the untranslated English key onto
|
|
* the card — "Test ABC 1 pieces" even on a German UI. This helper splits
|
|
* the amount from the unit and, when the unit is one of the canonical
|
|
* {@link DOSE_UNIT_KEYS}, swaps it for the localised label
|
|
* (`medications.wizard.steps.step3.unit.<key>`). A custom free-text dose
|
|
* the wizard never produced (e.g. "1 puff morning") passes through
|
|
* unchanged.
|
|
*
|
|
* Pure + SSR-safe: takes the `t` accessor as a parameter, no React hook.
