feat(brainstorm): rouvrir la note créée depuis une idée convertie

Quand une idée est déjà convertie en note:
- Badge 'Note Created →' cliquable dans le header de l'idée (ouvre le peek)
- Bouton 'Open Note →' remplace 'Create Note' (bordure emerald, fond vert)
- peek.open(convertedToNoteId) ouvre le drawer latéral avec la note
- L'utilisateur peut relire la note sans quitter le brainstorm
