Refactor EIP-7702 sender details and improve webhook error handling (#23)

- Renamed `account_address` to `eoa_address` in the `SessionKey` variant of `Eip7702Sender` for clarity and consistency.
- Updated the webhook error handling logic to use `StatusCode::TOO_MANY_REQUESTS` instead of a numeric comparison for better readability.
- Removed commented-out code in `confirm.rs` to clean up the file.

These changes enhance code clarity and maintainability in the EIP-7702 executor and webhook components.
