Major improvements to test robustness

[rookmate]

• Add chain randomization to tests. So now it won't always try to run the same test on the same chain
• Add option to include Arbitrum, OP and Base mainnets to the test chains (Set the environment variables ARBITRUM_RPC, BASE_RPC and/or OPTIMISM_RPC
• Transfer credits to the user wallet after the test finished (both by reverting or successful execution)
• Add labels to the foundry.toml to enable improved parsing when running cast run --la <TX_HASH>
• Improve awaitEvents and sendTransaction to log times to benchmark transactions
• Add deployment tests
