SCP user friendly exceptions

### Version

2.10.0

### Bug description

When using the SCP client to upload a file to a remote location that does not exist a `WindowClosedException` is raised instead of a more user friendly SCP exception detailing the reason of why the upload/download failed.

The snippet of code below raises a `WindowClosedException` exception when `/remote/path/that/does/not/exist` doesn't exist.
```
val session = sshClient.connect(
username,
hostname,
port
).verify(5000).session
session.auth().await(5000)

scpClient = ScpClientCreator.instance().createScpClient(session)
scpClient.upload("/local/path/file_name", "/remote/path/that/does/not/exist/file_name", options)
```

### Actual behavior

```
e = {WindowClosedException@37364} "org.apache.sshd.common.channel.WindowClosedException: Already closed: RemoteWindow[client](ChannelExec[id=0, recipient=0]-ClientSessionImpl[ifaur@localhost/127.0.0.1:2222])"

12 = {StackTraceElement@41991} "org.apache.sshd.scp.client.ScpClient.upload(ScpClient.java:106)"
```

### Expected behavior

a `SCPException` or even a basic `IOException` with a more relevant message:
- destination "/remote/path/that/does/not/exist/file_name" does not exist or could not be created
- "/remote/path/that/does/not/exist/file_name" no such file or directory

### Relevant log output

_No response_

### Other information

_No response_

Trace the SCP upload path from AbstractScpClient.upload and DefaultScpClient.runUpload through ScpHelper.send and ScpIoUtils.sendAcknowledgedCommand. Reproduce the missing-destination case, then ensure it reports a relevant SCPException or IOException with the destination and failure reason instead of WindowClosedException. Done means upload and download failures expose a user-facing error describing the missing or uncreatable path.
