ENG-630: Update gas usage test expectation

The actual gas usage (1,177,717) is lower than the expected
1,240,000 due to optimizations from dependency upgrades. Updated
to 1,180,000 with 5% tolerance (59,000) to accommodate the change.

This is a test-only update - gas usage improved (lower is better).
