Add Proxmox host role, WireGuard VPN, and public Gitea via Traefik HTTPS

Proxmox host role:
- Admin user setup, SSH hardening (port 2222, no root login)
- claude-code SFTP chroot user
- Unattended upgrades, DuckDNS dynamic DNS updater (vault-encrypted token)
- WireGuard VPN server (10.10.10.0/24) with Fedora client registered
- Proxmox firewall management via pvesh API (idempotent Python script)

Public Gitea exposure:
- Traefik: add HTTPS entrypoint, Let's Encrypt ACME (HTTP-01), StripPrefix
  middleware for /git subpath, HTTP→HTTPS redirect
- Gitea ROOT_URL updated to https://adyrem.duckdns.org/git/
- Pi-hole split DNS: adyrem.duckdns.org → 10.10.1.3 for internal hairpin bypass

SSH config fixes:
- StrictHostKeyChecking no → accept-new across all hosts
- Proxmox jump host: port 2222, user adyrem (root login disabled)
