Subject: [PATCH] feat: susun semula layout urus template sijil
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Panduan Template di bahagian atas, boleh lipat/kembang
- Template Aktif (kiri) bersebelahan Konfigurasi Teks (kanan) — col-lg-6
- Auto-detect portrait/landscape dari naturalWidth/naturalHeight imej
- Portrait: max-height 520px | Landscape: max-height 340px
- Badge orientasi (hijau=Landscape, biru=Portrait) dalam header kad
- Laras tinggi juga untuk pratonton upload form
