Erich Blume eb952aae01 P3: PostgreSQL disaster recovery test and borgmatic k8s-pg backup (#32)
## 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
- `ansible/roles/borgmatic/` - Added `local_path` and k8s-pg database entry
- `ansible/roles/postgresql/tasks/main.yml` - Added k8s-pg to `.pgpass`
- `argocd/apps/apps.yaml` - Disabled selfHeal
- `argocd/manifests/databases/blumeops-pg.yaml` - Added borgmatic managed role
- `argocd/manifests/databases/secret-borgmatic.yaml.tpl` - New secret template
- `pulumi/policy.hujson` - Added ACL grant for backup access

## Deployment and Testing
- [x] Borgmatic backup runs successfully
- [x] Miniflux data restored to k8s-pg (2 users, 2 feeds, 44 entries verified)
- [x] borgmatic user created in k8s-pg with pg_read_all_data role
- [x] Both localhost and k8s-pg databases in backup archive
- [x] zk documentation updated (borgmatic.md, postgresql.md)
- [ ] After merge: set blumeops-pg app back to main revision
