============================================================
TASK: Audit konsistensi response dan error handling di controller admin.

STANDAR WAJIB ADMIN CONTROLLER:
1. store() berhasil → redirect()->route('admin.X.index')->with('success', 'Berhasil disimpan.')
2. update() berhasil → redirect()->route('admin.X.edit', $model)->with('success', 'Berhasil diperbarui.')
3. destroy() berhasil → redirect()->route('admin.X.index')->with('success', 'Berhasil dihapus.')
4. SETIAP operasi yang bisa gagal HARUS ada try-catch
5. Image/file delete saat model di-destroy: Storage::delete($model->thumbnail)
6. Slug auto-generate dari name_id jika slug kosong
7. Pagination di index(): ->paginate(15)

CEK ProductController.php:
1. Apakah store() auto-generate slug dari name_id?
2. Apakah destroy() hapus file gambar dari storage sebelum delete model?
3. Apakah ada authorize() check atau policy?
4. Apakah ada try-catch di store/update?

CEK BlogPostController.php:
1. Apakah published_at di-set ke now() saat status diubah ke 'published'?
2. Apakah thumbnail lama dihapus saat upload thumbnail baru?

CEK SiteSettingController.php:
1. Apakah update() loop semua key dan updateOrCreate()?
2. Apakah image type disimpan sebagai path relative (bukan full URL)?

Tulis fix untuk semua inkonsistensi.
