CTO Agent fd0b589c10 Document Hetzner Load Balancer architecture for Stalwart
Added comprehensive documentation of the two-tier load balancing setup:
- Hetzner Cloud Load Balancer (external layer, managed by Hetzner CCM)
- Kubernetes LoadBalancer services (internal layer, k3s ServiceLB)

Key points documented:
- Traffic flow from external client through both LB layers to pod
- Why LoadBalancer service type is required (CCM integration)
- Historical context of the migration from hostPort to Hetzner LB
- Service definitions and port configurations

Updated:
- apps/stalwart/README.md: Added Network Architecture section
- infrastructure/networking/NETWORK_ARCHITECTURE.md: Enhanced Stalwart
  section with two-tier architecture details and updated traffic flows

Resolves documentation gap identified in DEV-439.
