feat: initialize serverAppConfigs with podman stacks for Dankserver and Dankclaw

- Dankserver stack: RomM, Copyparty, Calibre-Web, node-exporter
- Dankclaw stack: Gluetun VPN (SearXNG tunnel), SearXNG+Valkey, ComfyUI
  (CPU backend), OpenWebUI, Hermes, Gitea+Postgres (migrated), Caddy
  reverse proxy, Grafana+Prometheus+Loki+Alloy observability
- Caddyfiles with .local hostname convention and basicauth homepage
- bind-mount storage policy, no named volumes
- deploy.sh mirroring vllmScripts git workflow (push -> pull -> restart -> health)
- docs/ Obsidian vault: per-service docs from frank-default-small research
  subagents (promtail EOL -> Alloy; gitea SECRET_KEY preservation; ComfyUI --cpu)
- bats test suite at 6 seams — 22 tests green

+# Backblaze Integration
+
+Off-site backup plan for the bind-mounted data on both hosts. **Deferred**: research only, not implemented yet.
+
+## Goal
+
+Back up critical data to Backblaze B2:
+- Calibre library (Dankserver)
+- ComfyUI models (Dankclaw)
+- Gitea data, repos, DB (Dankclaw)
+- Homepage/stack configs (this repo — already versioned in git)
+
+## Approach (research direction)
+
+| Option | Fit |
+|--------|-----|
+| `restic` + B2 | Best fit: dedupe, encryption, snapshots, low cost. Single static binary, works with podman host. |
+| `borg` + borgbase | Alternative; borgbase is more expensive per TB than B2. |
+| rclone + B2 | Good for file sync, no snapshot/dedupe semantics. |
+| podman volume driver for B2 | Niche, immature. Not recommended. |
+
+## Shape of the Implementation (future)
+
+- `scripts/backup.sh` on each host, run by systemd timer or cron.
+- `restic -r b2:bucket:path backup /opt/...`
+- `RESTIC_PASSWORD` in the host `.env`, never in the repo.
+- Restore procedure documented once the backup job exists.
+
+## Next Steps
+
+1. Create a B2 bucket + application key.
+2. Draft `scripts/backup.sh` and a systemd timer unit.
+3. Run a test restore.
