PR Summary

Low Risk
Low risk rename-only change: updates type names and call sites without changing oracle query/caching logic. Main risk is missed references causing compile or integration breakages in downstream crates.

Overview
Renames the ETH→STRK oracle client type from EthToStrkOracleClient to PriceOracleClient and updates its PriceOracleClientTrait implementation accordingly.

All internal call sites are updated to use the new name, including the oracle unit tests and L1GasPriceProvider::new_with_oracle construction path.
