Add self-hosted git server with SSH and cgit web UI

Deploy a self-hosted git repository solution to replace external Codeberg dependency.

Components:
- SSH git server: Alpine-based container with OpenSSH and git
- cgit web UI: Browse repositories at cgit.f3s.buetow.org
- Single pod design: git-server + cgit containers sharing storage

Infrastructure:
- Docker image in git-server/docker-image/ with Justfile build automation
- Helm chart in git-server/helm-chart/ for Kubernetes deployment
- 5Gi ReadWriteMany PVC for NFS-backed repository storage
- ClusterIP service for ArgoCD internal access
- NodePort 30022 for external SSH push access
- Traefik ingress for cgit web UI

ArgoCD Application manifest deployed to cicd namespace.

Note: SSH keys must be created as Kubernetes secrets manually, not in git.
