Fix stale docs and shell quoting in devpi start script

- ArgoCD ref: correct Git Source URL to forge.ops.eblu.me:2222
- Authentik ref: add Zot as active OIDC client, blueprint, and secret
- Federated login: remove Zot from Future Work (completed in PR #236)
- devpi/start.sh: use bash array for command building (proper quoting)
