# 2026-05-11 10:51 - Setup User UUID dan Relasi user_id

## Perubahan
- Mengubah primary key `users` dari auto increment ke UUID (`id` bertipe uuid primary key).
- Mengubah seluruh kolom relasi `user_id` utama di migration dari `foreignId` menjadi `foreignUuid`.
- Menyesuaikan `sessions.user_id` menjadi UUID nullable index.
- Mengaktifkan UUID di model `User` (`HasUuids`, `keyType=string`, `incrementing=false`).
- Menyesuaikan beberapa controller yang sebelumnya mengasumsikan `user_id` numerik (cast int) agar aman untuk UUID string.
- Menyesuaikan filter karyawan di halaman izin agar mendukung ID UUID string.
