bug: special chars in filename break file sending in docker image

[smashah]

Doesn't work:

{
  "args": {
    "to": "1111@c.us",
    "file": "https://www.africau.edu/images/default/sample.pdf",
    "filename": "testé.pdf",
    "waitForId": true
  }
}

Works:

{
  "args": {
    "to": "1111@c.us",
    "file": "https://www.africau.edu/images/default/sample.pdf",
    "filename": "test.pdf",
    "waitForId": true
  }
}

The sendfile(image) process fails on the uploadFile stage within the docker container.

Fix:

Sanitize the filename only when creating the temp file and uploading the file. Use the original filename when sending the file via wapi.

fixed in 4.59.0
