Tambahkan validasi form untuk data debitur

- Menambahkan properti `id` pada elemen form untuk mempermudah manipulasi DOM.
- Menandai field wajib dengan tanda bintang (*) dan memastikan validasi untuk field yang diperlukan.
- Menambahkan script JavaScript untuk validasi input form secara dinamis, termasuk cek keberadaan data dan memberikan feedback error real-time.
- Menambahkan event listener untuk memastikan semua field tervalidasi sebelum pengiriman form.
