//! Tests for PriceSource trait and implementations
//!
//! Tests focus on:
//! - Trait object safety (PriceSource can be used as Box<dyn PriceSource>)
//! - Event topic configuration
//!
//! Note: Swap extraction and filtering logic is tested via PriceCalculator
//! integration tests with MockPriceSource.
