Subject: [PATCH 1/2] fix: allow 404 status code in OPTIONS request for WebDAV
 auth

Some WebDAV servers return a 404 status for the OPTIONS request if the
endpoint is not explicitly configured, even though authentication may
still be valid. Previously, the implementation only allowed a 200
response and threw an error otherwise.

This fix updates the authentication check to also accept 404, preventing
unnecessary authentication failures and improving compatibility with a
wider range of WebDAV servers.
