Pull Request Overview

This PR refactors the state override mechanism for eth_call to apply overrides directly to original account states during State object construction, rather than applying them after construction. This ensures that tracers (PreState and StateDiff) capture the correct pre-execution state including overrides.

Key Changes:

• Moved state override application logic from eth_call.cpp into the State constructor
• Added a new templated State constructor that accepts state overrides as a parameter
• Modified state overrides to work directly with OriginalAccountState instead of using state mutation methods
