Subject: [PATCH] Add live SFTPGo WebDAV test (real 2nd WebDAV server via
 dav.khodak.me)

Tests the app's SFTPGo provider (WebDavProvider) end-to-end against a real
SFTPGo server over its exposed WebDAV URL: connect, mkdir, atomic upload,
list, download, overwrite, non-ASCII filename, delete. Validates the WebDAV
code path against a non-Nextcloud server. Creds via -e davUrl/davUser/davPass.
