	/// ## Test Setup:
	/// - Creates 1 transaction with 1 ContractEmitted event
	/// - Event contains `d` total bytes of data across data field and topics
	///
	/// ## Usage:
	/// Measures the per-byte event data processing overhead during finalization
	/// - Fixed cost: `on_finalize_per_event_data(0)` - baseline cost with empty event
	/// - Per byte: `on_finalize_per_event_data(d)` - linear scaling with data size
