Pieter 79635eeece feat: Add private network architecture with NAT gateway
Enable deployment of client servers without public IPs using private
network (10.0.0.0/16) with NAT gateway via edge server.

## Infrastructure Changes:

### Terraform (tofu/):
- **network.tf**: Define private network and subnet (10.0.0.0/24)
  - NAT gateway route through edge server
  - Firewall rules for client servers

- **main.tf**: Support private-only servers
  - Optional public_ip_enabled flag per client
  - Dynamic network block for private IP assignment
  - User-data templates for public vs private servers

- **user-data-*.yml**: Cloud-init templates
  - Private servers: Configure default route via NAT gateway
  - Public servers: Standard configuration

- **dns.tf**: Update DNS to support edge routing
  - Client domains point to edge server IP
  - Wildcard DNS for subdomains

- **variables.tf**: Add private_ip and public_ip_enabled options

### Ansible:
- **deploy.yml**: Add diun and kuma roles to deployment

## Benefits:
- Cost savings: No public IP needed for each client
- Scalability: No public IP exhaustion limits
- Security: Clients not directly exposed to internet
- Centralized SSL: All TLS termination at edge
