feat: set_hostname — update /etc/hostname, /etc/hosts, cert, Postfix

Implements set_hostname on ProxmoxSystemMixin: 1. Writes /etc/hostname (short name, base64-safe transfer) 2. Replaces old hostname in /etc/hosts via Python regex + base64 3. Updates /etc/mailname if present 4. Updates Postfix myhostname via postconf -e if installed 5. Applies hostname immediately at runtime via hostname(1) 6. Regenerates Proxmox node TLS certificate via pvecm updatecerts -f (falls back to pvenode cert create → pveproxy restart) Accepts bare hostname or FQDN. A reboot is required for the Proxmox node name to update in the web UI / cluster — the driver logs this. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
