✨(lpj/nilai-plafond): Tambah field biaya, validasi, transaksi DB, ekspor, dan tampilan

- Menambahkan kolom biaya ke seluruh alur Nilai Plafond (model, request, controller, views, export, dan migrasi)
- Update model NilaiPlafond agar field biaya bisa di-mass assign ($fillable)
- Tambah validasi baru 'biaya' (nullable|numeric|min:0) di NilaiPlafondRequest
- Terapkan transaksi DB (beginTransaction, commit, rollback) pada store/update/destroy di controller
- Tambahkan kolom biaya ke view create, edit, dan datatable index dengan format Rupiah dan tooltip nilai mentah
- Tambah header & mapping kolom biaya di NilaiPlafondExport agar muncul di hasil export Excel
- Tambah migrasi kolom biaya bertipe decimal(15,2) nullable dengan rollback support
- Tambahkan logging detail (Log::info & Log::error) di setiap proses utama controller
- Pastikan pencarian kolom biaya pada datatables menggunakan CAST ke TEXT untuk kompatibilitas PostgreSQL
