Cap cryptography dependency to prevent pyOpenSSL/certbot conflicts

Global pip install of sovp pulled cryptography's latest release, which
shadowed the OS-packaged version and broke pyOpenSSL/certbot/josepy on
a server. Bound to the range pyOpenSSL 23.x (Ubuntu 24.04's apt version)
actually supports: >=38.0.0,!=40.0.0,!=40.0.1,<42.
