PR Summary

Low Risk
This is a module rename/update of import paths with no behavioral changes, so risk is low aside from potential missed references to the old eth_to_strk_oracle module name.

Overview
Renames the eth_to_strk_oracle module to price_oracle and updates call sites/tests (l1_gas_price_provider.rs, eth_to_strk_oracle_test.rs, and lib.rs) to import PriceOracleClient/PriceOracleConfig from the new module path.
