feat(helm): complete chart normalization with ConfigMap, HPA, and OCI migration

- Added debug mode, structured ConfigMap pattern, and README to all charts
- Migrated all flat-structure charts to hierarchical values under chartname key
- Fixed templates to use correct hierarchical paths
- Renamed helm-rustical key to rustical, added HPA support
- Fixed ingress YAML parsing (oxicloud), nested env vars (rustical)
- Pushed all normalized charts to OCI registry as 1.0.0+ and updated ArgoCD apps
