fix: disable balance check for eth_call RPCs

[qj0r9j0vc2]

Summary

• eth_call, eth_estimateGas, and debug_traceCall were failing with LackOfFundForMaxFee when the caller had insufficient balance, even though these are read-only simulations
• Enable revm's optional_balance_check feature and set disable_balance_check = true in all 3 EVM simulation paths
• Nonce check was already correctly disabled; this adds the missing balance check counterpart

Test plan

• cargo build passes
• cargo test passes (all crates, 0 failures)
• Manual: cast call <contract> "balanceOf(address)" <addr> --rpc-url <node> returns data instead of LackOfFundForMaxFee error
