feat: restore operator WIP — PMM JSON sync entrypoint, dotenv RPC trim + secrets, pool env alignment

- Resolve stash: merge load_deployment_env path with secure-secrets and CR/LF RPC strip
- create-pmm-full-mesh-chain138.sh delegates to sync-chain138-pmm-pools-from-json.sh
- env.additions.example: canonical PMM pool defaults (cUSDT/USDT per crosscheck)
- Include Chain138 scripts, official mirror deploy scaffolding, and prior staged changes
