feat(records): surface allergies + family history in Settings

Add a new "Medical history" (Anamnese) Settings section that hosts the two
structured-record managers — allergies and family history — each a
list + add/edit sheet + delete-with-confirm built on the shared query-key
factory and the ResponsiveSheet pattern. It sits between the illness journal
and the preventive-care reminders and is always shown (not module-gated, like
Vorsorge), since these are foundational health-profile records.

The section carries a plain non-diagnostic note ("your own records, not a
medical diagnosis"). Full i18n across all six locales (de/en/es/fr/it/pl).
