test(M8): tests unitaires pour AgendaComparator (17 cas)

Couvre : agendas vides, ADDED/REMOVED/MODIFIED, tolérance ±15 min
(bord inclusif), normalisation NFKC des matières, matching multi-candidats
par plus petit id, comparaison ordre-insensible des enseignants/salles,
statut != NORMAL, REMOVED par existence (pas par sélection), ordre
déterministe et idempotence. Couverture de sync/diff.py : 92%.
