init: projet complet copymail pour Raspberry Pi

Stack: Nginx + PHP 8.2 + MariaDB + Postfix + Dovecot + Samba
- install.sh: script installation automatisé pour RPi OS Bookworm
- Interface web: visionneuse mails + admin (comptes, domaine, dashboard)
- Chaque compte mail génère automatiquement un share Samba
- Processeur cron: extraction pièces jointes via zbateson/mail-mime-parser
- Zéro injection SQL (PDO + prepared statements)
