AssetManager 0.5.4.8

- Fixes the common Windows job dispatcher used by software inventory, registry jobs and PowerShell job definitions.
- Sends PowerShell source through MeshCtrl's native `--powershell` channel instead of nesting `cmd.exe` and `powershell.exe -EncodedCommand`.
- Uses `--reply` so MeshCtrl waits for the remote agent response rather than returning only the server acknowledgement `OK`.
- Keeps GZip/Base64 compression, but the compact bootstrap is now valid PowerShell source executed directly by the agent.
- Dispatch diagnostics show whether native PowerShell with reply was used.
