V2.8 Fix: „Erneut verarbeiten" setzt DB-Status vor Mini-Lauf zurück

Das Problem: Der „Erneut verarbeiten"-Button startete einen Mini-Lauf,
ohne den DB-Status der selektierten Dateien zurückzusetzen. Dateien mit
FAILED_FINAL-Status wurden daher vom Use Case übersprungen.

Die Lösung:
1. Neue Methode startReprocessing() in GuiBatchRunCoordinator, die
   resetPort.reset() SYNCHRON vor dem Mini-Lauf aufruft.
2. handleReprocessSelected() in GuiBatchRunTab nutzt jetzt
   startReprocessing() statt startMiniRun() direkt.
3. Test-Fix: noOpReset muss die Fingerprints in der erfolgreich-zurückgesetzt-
   Liste enthalten, damit successCount() > 0 ist.

Spec-Konformität:
- Reset erfolgt synchron vor dem Worker-Thread-Start
- Keine neue Architektur-Verletzung
- Hexagonale Architektur bleibt sauber (Port/Adapter)
