PR Summary

Low Risk
Changes are limited to local monitoring deployment scripts and compose config injection; default behavior without PRAGMA_API_KEY is unchanged, and secrets are supplied only via environment variables.

Overview
The local monitoring stack can now drive live Pragma exchange rates for L1 gas pricing when PRAGMA_API_KEY is set, instead of always using the in-compose dummy oracle.

deploy_local_stack.sh exports default Pragma eth/strk and strk/usd URLs and, when an API key is present, builds url_header_list values (URL + x-api-key) for the sequencer config injector; without a key it logs that the dummy oracle is used. docker-compose.yml config_injector now injects both eth_to_strk and strk_to_usd oracle URLs from ${ETH_STRK_ORACLE_URL_HEADERS} / ${STRK_USD_ORACLE_URL_HEADERS} with the same dummy fallback as before, and sets lag_interval_seconds (default 60) for each oracle via optional env overrides.

Integration/CI paths that do not set these variables keep the existing dummy oracle behavior.
