Tambah fitur otorisasi SLA

- Menambahkan view baru untuk otorisasi SLA (`sla.blade.php` dan `index-sla.blade.php`).
- Menambahkan route baru untuk data datatables SLA (`sla.datatables`).
- Mengupdate controller (`PenilaianController`, `SLAController`) untuk mendukung alur otorisasi SLA.
- Menyesuaikan model `Authorization` guna kebutuhan SLA.
