feat(export): Bestandsbuch für Tierarzneimittel nach Art. 108 VO (EU) 2019/6

- Treatment records supplier, purchase proof and prescribing vet, and
  keeps the apiary the colony stood at on the treatment day.
- Holder name and address in site settings (never in public output;
  regression test in public.service.spec).
- treatment-log.pdf: one sheet per apiary, identical treatments grouped,
  missing mandatory fields printed as FEHLT, uncertain locations marked.
- Shared PDF table helpers extracted from the record card.
