feat(notes): vues structurées tableau/kanban, flashcards et MCP robuste

Ajoute la base organisable par carnet (schéma, champs partagés, valeurs par note)
avec activation guidée, tableau éditable, kanban et suppression de colonnes.
Corrige le multiselect en vue tableau et enrichit sidebar, grille et i18n FR/EN.
Inclut aussi les améliorations flashcards SM-2, l'audit consentement IA et la
robustesse du serveur MCP (config, validation, rate-limit, métriques).
