Fix configmap source path resolution from spec values

Spec configmaps with explicit paths (e.g. "stack-orchestrator/compose/maintenance")
were ignored — only the key name was used to look up under config/.
Now resolves the spec value relative to the stack root when provided.
Values starting with ./ (auto-discovered by deploy init) still use
the existing config/ directory convention.
