feat(auth): bring opaque (RFC 9807) auth

OPAQUE (RFC 9807) implementation (using `opaque-ke` crate)

    with opaque authentfication, server will never receive the password (in the auth=password mode)
    this is a must have to create trust with users to permit end to end encryption in the future
    (we cannot know if user use the same password/passphrase for his asymetric key or his oxicloud auth,
    this is why server must never have the password)

    pass1: prepare server
