feat: add BK admin panel with complete CRUD operations and student management

- Create BKController with dashboard, students, chat history, recommendations, and jurusan management
- Add 8 BK panel views: students list/detail, chat history, riwayat rekomendasi/chatbot, jurusan CRUD, profil
- Add 15 BK routes with auth and isBK middleware protection
- Update AdminSeeder with 8+ char passwords and valid email format
- Add database migrations for chat history improvements
- Update various controllers and models for BK panel integration
- Remove sidebar Profil duplication, keep navbar dropdown only
