fix: perbaiki item dan total pecah baris di struk thermal 

Library flutter_esc_pos_utils mengirim ESC a (align) di tengah
     baris
     pada generator.row(), menyebabkan kolom right-aligned tercetak di
     baris baru. Ganti semua row() campuran left+right alignment
     dengan
     text() + _padRow() (manual space padding 32 char) agar tidak ada
     perintah ESC a di tengah baris.

     - Tambah helper _padRow(left, right) untuk padding 32 karakter
     - Item: deskripsi 1 baris (width 12), qty×price + total 1 baris
     - Subtotal, TOTAL, BAYAR, KEMBALI/TIP, KURANG: text() + _padRow()
