Add PveSession, PveAuthenticator, PveVersion, and PveAuthMode. Support
ticket-based auth (username/password with 2hr expiry) and API token auth
(USER@REALM!TOKENID=UUID format). Version detection on connect via
GET /api2/json/version. Custom exception types for API errors, expired
sessions, missing connections, version mismatches, and task failures.
