fix(CA): using the bundled simulation for allowance and bridging transactions

[geekbrother]

Description

This PR changes the approach of the gas estimation from using the eth_estimateGas for the approval transaction and simulation for the bridging transaction to the bundled simulation for the approval and bridging transaction together.

The following changes were made:

• The bundled simulation provider trait was added and the implementation for the Tenderly provider;
• Flow of the estimation changed to simulate both transactions in a bundle;
• The proper check for the transaction simulation failure was added;
• The proper error handling for the simulation provider error and the simulation failure added;
• The estimated gas slippage decreased to 20% to cover the volatility between the estimation and the transaction execution.

How Has This Been Tested?

The current integration test for the gas estimation shouldn't be zero which is the default if the simulation was not fulfilled.

Due Diligence

• Breaking change
• Requires a documentation update
• Requires a e2e/integration test update
