fix: backend dead code + bug destroy + nettoyage legacy

- Suppression forgottenPassword/resetPassword (dead code, routes jamais câblées)
- Suppression nodemailer (plus utilisé)
- Fix destroy() : getById() → read() (bug — méthode inexistante)
- Ajout getByNickname() dans UserManager (appelé mais manquant)
- README rebrandé Clickerz/Tetardtek
- Commentaire legacy WildCoinContext supprimé
- SPRINT1.md : ref Xmass nettoyée
