completedFdis property
FDI set of teeth already completed (e.g. {18, 17, 16, 15, 14}).
The library uses int FDI codes throughout (per ISO 3950 / FDI World
Dental Federation notation). The task spec listed String FDI keys —
int was preferred to match the widely-used numeric convention and to
keep the API compatible with smart-mirror's existing sector logic.
