[EASY] Simulate settlement tx before submitting (#3166)

# Description
On the `base` network, there are more settlement tx onchain reverts than
expected. According to the logs, we couldn't catch those reverts using
`estimate_gas` calls that happen only **after** the tx is submitted to
the mempool. The tx also gets simulated before submitting a solution to
the competition. However, the delay between that event and the actual
execution can cause the tx to become invalid later. So, this PR adds
additional `estimate_gas` call **before** the tx gets submitted.

## How to test
