Fix #70264: CLI server directory traversal
On Windows the built-in webserver doesn't prevent directory traversal when
backslashes are used as path component separators. Even though that is not a
security issue (the CLI webserver is meant for testing only), we fix that by
replacing backslashes in the path with slashes on Windows, because backslashes
may be valid characters for file names on other systems, but not on Windows.
