Add the `/api/allergies` and `/api/family-history` endpoints (list / create /
read / update / soft-delete), each wrapped in `apiHandler` with Zod
`safeParse` + `returnAllZodIssues`. `userId` is always narrowed from the
session/Bearer — never a body field — and the Prisma `data` is built
field-by-field (no mass assignment). Creates wrap in `withIdempotency`. The
free-text reaction/note are encrypted before write and decrypted fail-soft on
read via the server-authoritative DTOs.
Register the query-key factory entries and the OpenAPI route tables (new
`Records` tag); regenerate `docs/api/openapi.yaml`.
