feat: add equipment area grouping, criticality, and batch inspection

- Add area and criticality fields to Machine model with DB migration
- Add batch inspection endpoint (POST /inspections/batch) for area-wide inspection creation
- Rewrite MachineList with area grouping, criticality badges, and batch inspect button
- Update machine create/edit forms with area and criticality fields
- Update seed data with area/criticality values for all tenants
