Perbarui sintaks Dart dan perbaiki opacity warna

- Ganti `Key? key` dengan `super.key` di berbagai tampilan
- Gunakan `withAlpha()` sebagai pengganti `withOpacity()` untuk transparansi warna
- Lakukan penyesuaian kecil pada tata letak dan styling komponen
- Hapus impor yang tidak digunakan
- Sederhanakan beberapa bagian kode dashboard
