Erich Blume e4a8405de7 Observability cleanup and k8s service monitoring (#43) (#43)
## Summary
- Remove stale `/opt/homebrew/var/loki` from borgmatic backup (Loki migrated to k8s)
- Add Alloy k8s DaemonSet for automatic pod log collection with auto-discovery
- Add blackbox probes for miniflux, kiwix, transmission, devpi, argocd
- Add transmission-exporter sidecar for full metrics (speed, torrent counts, ratios)
- Replace stale devpi dashboard with probe-based metrics (status, response time, uptime)
- Add unified "K8s Services Health" dashboard for service uptime/response monitoring

## Manual cleanup already performed
- Deleted stale textfile metrics on indri: `devpi.prom`, `transmission.prom`
- Deleted stale data directories on indri: `/opt/homebrew/var/loki/`, `/opt/homebrew/var/prometheus/`

## Deployment and Testing
- [x] Sync `apps` application to pick up new alloy-k8s app
- [x] Deploy alloy-k8s on feature branch: `argocd app set alloy-k8s --revision feature/observability-cleanup && argocd app sync alloy-k8s`
- [x] Deploy torrent on feature branch (for transmission exporter): `argocd app set torrent --revision feature/observability-cleanup && argocd app sync torrent`
- [x] Deploy prometheus on feature branch (for new scrape config): `argocd app set prometheus --revision feature/observability-cleanup && argocd app sync prometheus`
- [x] Deploy grafana-config on feature branch (for dashboards): `argocd app set grafana-config --revision feature/observability-cleanup && argocd app sync grafana-config`
- [x] Verify pod logs appear in Loki/Grafana
- [x] Verify transmission metrics appear in Prometheus
- [x] Verify service probe metrics appear in Prometheus
- [x] Run `mise run provision-indri -- --tags borgmatic` to update borgmatic config
- [ ] After merge, reset apps to main and resync
