## Summary
- Fixed borgmatic `borg: command not found` by adding `local_path` config option
- Successfully tested disaster recovery: restored miniflux data from borgmatic backup to k8s-pg
- Added borgmatic user to k8s-pg via CloudNativePG managed roles
- Configured borgmatic to backup both localhost and k8s-pg PostgreSQL databases
- Added Tailscale ACL grant for `tag:homelab` → `tag:k8s` on port 5432
- Disabled selfHeal on apps app to allow manual revision changes during development

## Changes

- `argocd/manifests/databases/secret-borgmatic.yaml.tpl` - New secret template
