AssetManager 0.5.4.7

- PowerShell jobs use compressed transport to avoid Windows/MeshCtrl command-line truncation.
- Immediate running callback proves that execution started on the client.
- MeshCtrl dispatch diagnostics include node id, command length, script length, SHA-256, timestamps and return code.
- German navigation consistently uses “Software und Jobs”.
- Job-definition checkboxes are left-aligned and stacked cleanly.
