Problem: DeparturesManager.displayDepartures() used JSON.parse(JSON.stringify(departures)) to deep clone departure data. This is slow and loses Date objects, undefined values, and other non-JSON types.

Solution: Replaced with structuredClone(departures) which is the modern browser/Node API for deep cloning that preserves all object types.
