Fix: Erreurs 500 lors mise à jour notes - SQL dynamique non converti

Problème: PUT /api/notes/:id retourne 500 Internal Server Error
- Script convert-sql-to-postgres.js a manqué les requêtes SQL dynamiques
- Routes utilisaient encore syntaxe SQLite (?) dans les updates dynamiques
- Erreur: "bind message supplies 2 parameters, but prepared statement requires 0"

Fichiers corrigés:
- routes/notes.routes.js:219-236 (PUT /api/notes/:id)
- routes/notes.routes.js:444-469 (PUT /api/notes/todos/:todoId)
- routes/todos.routes.js:92-111 (PUT /api/todos/:id)

Solution:
- Ajout compteur paramCount pour numérotation PostgreSQL
- Remplacement ? par $1, $2, $3... dans updates dynamiques
- Exemple: 'title = ?' → `title = $${paramCount}`

Résultat: Notes peuvent maintenant être éditées sans erreur 500
