Tambah fitur riwayat permohonan

Menambahkan migrasi database, model, dan service untuk mencatat riwayat setiap permohonan. Migrasi menciptakan tabel `permohonan_histories` dengan menyimpan detail tentang status, keterangan, perubahan permohonan (sebelum dan sesudah), dan informasi file terkait. Model `PermohonanHistory` mengatur relasi dengan model `Permohonan` dan `User`. Service `PermohonanHistoryService` menangani pembuatan riwayat baru serta penanganan file terkait dan error handling yang memadai.
