feat: input field saiz font No IC dalam konfigurasi template

- Tambah fields[name][ic_font_size] dalam form — baris: Warna | Saiz Font No IC | Align
- Default: 70% daripada saiz font nama (sebelum ini hardcode 50%)
- loadPreview() hantar ic_font_size terkini ke endpoint pratonton
- writeIcBelow() baca ic_font_size dari config, fallback 70% jika tiada
- Validasi updateConfig: ic_font_size nullable|integer|min:8|max:200
