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

 ### PMM (Chain 138) completion checklist
 
 1. Set **DODO_VENDING_MACHINE_ADDRESS** in `.env` to the DODO DVM factory address on Chain 138. **Chain 138 is not in DODO’s official list** — see [DVM_DEPLOYMENT_CHECK.md](DVM_DEPLOYMENT_CHECK.md). Deploy the factory yourself from [DODOEX](https://github.com/DODOEX) or use an existing deployment if available.
-2. Set **OFFICIAL_USDT_ADDRESS** and **OFFICIAL_USDC_ADDRESS** to the official or wrapped USDT/USDC token addresses on Chain 138 (already in .env as reference; replace with Chain 138 addresses if different).
+2. Set **OFFICIAL_USDT_ADDRESS** and **OFFICIAL_USDC_ADDRESS** to the live Chain 138 quote-side mirror stables:
+   - `OFFICIAL_USDT_ADDRESS=0x004b63A7B5b0E06f6bB6adb4a5F9f590BF3182D1`
+   - `OFFICIAL_USDC_ADDRESS=0x71D6687F38b93CCad569Fa6352c876eea967201b`
 3. Run: `bash scripts/deployment/deploy-all-mainnets-with-mapper-oracle-pmm.sh pmm` to deploy DODOPMMIntegration.
 4. Set **DODOPMM_INTEGRATION_ADDRESS** (or DODO_PMM_INTEGRATION) in .env from the deploy output, then create pools:
    - cUSDT/USDT and cUSDC/USDC: call `createCUSDTUSDTPool` and `createCUSDCUSDCPool` on the integration (see `docs/integration/DODO_PMM_INTEGRATION.md`).
