Produk kini punya cara jual `unit` (cacah) atau `weight` (timbangan), mengikuti kontrak backend di docs/integration-weight-based-products.md. - tipe SellBy, domain/infrastructure unit baru, dan endpoint /api/v1/units - dialog input berat saat produk timbangan ditambahkan ke keranjang - tiap penimbangan jadi baris keranjang sendiri; total baris dihitung berat x harga satuan, sedangkan produk cacah tetap digabung - request ke backend mengirim quantity 1 dan membawa berat - migrasi DB v3: kolom sell_by, unit_id, unit_name, unit_abbreviation di tabel products supaya satuan tetap tampil saat offline - tampilan keranjang, struk, split bill, void, dan refund memakai berat - test/weight_based_products_test.dart menutup perilaku di atas (9 test) Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
