Fix: Progress-Timer zeigte negative Zahlen (-58:-10)

Ursache: Server sendete started_at als Lokalzeit (Europe/Berlin),
aber der Client interpretierte es als UTC via parseUTC().
Bei UTC+1 lag die Startzeit dadurch 1 Stunde in der Zukunft.

- orchestrator.py: started_at in WebSocket-Nachrichten als echtes UTC
  (ISO 8601 mit Z-Suffix) senden, DB-Timestamps bleiben Lokalzeit
- components.js: elapsed auf min. 0 clampen als Sicherheitsnetz
