Auto-deduct spice inventory when batch is created/updated/deleted
- Add size_id, units_produced, quantity_g to batches table
- quantity_g auto-calculated from units × packing size on save
- Batch model deducts spice quantities on create, reverses on delete,
  recalculates on update when relevant fields change
- Batch form shows live total weight preview
- Chargen table shows units + grams produced
