Remove terraform_remote_state data sources that are declared but never referenced elsewhere in the generated code

Rationale: Unused remote state blocks add unnecessary upstream dependencies, clutter deploy.sh preflight checks, and confuse QA review. If a data source name does not appear outside its own block, it serves no purpose.
Agents: terraform-agent
