Temp: Use folder-based image names to match existing registry [skip ci]

This is a temporary workaround to test Flux reconciliation.
The registry currently has images stored with folder names (auth, tenant, etc.)
instead of service names (auth-service, tenant-service, etc.).

The permanent fix in task-kaniko-build.yaml will push with correct names
on the next full pipeline run.
