PR Summary

Low Risk
Test-only refactor in flow tests; the fee-transfer test’s initial state is slightly richer but assertions are unchanged.

Overview
Refactors os_resources_test.rs by pulling shared test harness setup into setup_test_builder and an OsResourcesTestSetup struct, so test_fee_transfer_syscalls and test_os_resources_regression no longer duplicate the same boilerplate.

The helper centralizes deploying and funding the OS-resources account contract, forcing step tracking via min_sierra_version_for_sierra_gas = (99, 99, 99), declaring/deploying the stable measurement contract, and advancing to the next block. An optional raw_vc argument optionally **assert_eq!**s versioned constants against the block context (used by the regression test).

test_fee_transfer_syscalls now calls the shared helper with None instead of TestBuilder::create_standard, so it runs on the same richer initial state as the regression test (stable contract + block advance), while still only asserting fee-transfer syscalls on the measurement invoke.
