feat: multi-subcategory questions, statistics hardening, seeded lab values
Questions can belong to additional subcategories (junction table, counts, builder/bank filters, edit UI chips); response statistics dedupe duplicate options, match case-insensitively and exclude obsolete answers; AI question classification is command-line only (UI trigger removed); lab reference seed script with cited public pediatric ranges. Migration h1c2d3e4f506. 55 backend and 88 frontend tests pass.
