Description

In addition to setting starting_gas_price the node also requires us to pass --gas-price-change-percent 0 for the set price to remain static. We should forward this parameter through our NodeConfig and update the can_setup_static_gas_price to test to verify that the price remains stable after producing a block.

Research direction
Examine the existing `NodeConfig` type and the `starting gas price` field. Find where the ` gas price change percent` parameter is set when launching the node. Modify `NodeConfig` to include a new field for `gas price change percent` or a static gas price flag. Update the test `can setup static gas price` to verify that the price remains static. Review existing test helpers and the node launch command.
