Fix: Installer self-contained Publish + Selbstbereinigung vor Install (v2.5.0)

Browse Source 
- dotnet publish lief zuvor mit --self-contained false → Installer nur 2MB
  ohne .NET-Runtime, schlägt auf Rechnern ohne .NET 8 fehl. Jetzt wieder
  self-contained Single-File wie historische Versionen (~53MB)
- setup.iss: Vor Installation werden jetzt automatisch verwaiste
  IT-Nexus-Agent.exe Prozesse gekillt und Reste eines laufenden
  Self-Update-Zyklus (update.cmd, heruntergeladener Installer) entfernt
- Behebt Installations-Instabilität durch File-Locks bei Upgrades
