feat(quiz): perbaikan refresh quiz + enhancement UI kuis 

- QUIZ-01: beforeunload hanya kirim beacon (tanpa finalisasi state) sehingga
  Cancel dialog membatalkan reload dan quiz lanjut; beforeNavigate tidak lagi
  memfinalisasi untuk tipe 'leave' (full-page unload/reload); review
  disembunyikan untuk page_unload (display policy anti-eksploitasi)
- QUIZ-02: opsi MCQ tampil 2-kolom grid (single-col untuk <=2 pilihan,
  fallback 1 kolom di mobile sempit)
- QUIZ-03: hapus info "soal X dari Y / X dijawab" + progress bar dari
  workspace dan question view
- QUIZ-04: opsi tinggi workspace mobile hide/30%/50%/70%/full dengan
  stepUp/stepDown untuk swipe & tombol resize
- QUIZ-05: workspace flashcard hanya 2 tombol "Sudah Mengerti"/"Tidak
  Mengerti" (tracking understood), indikator di summary review
