fix(privacyidea): add PI_ADDRESS/PI_PORT; switch readiness probe to tcpSocket

gpappsoft entrypoint requires PI_ADDRESS and PI_PORT env vars to build
the gunicorn bind argument. Without them the container crashes immediately.

/token/ returns 401 for unauthenticated GET requests so the httpGet
readiness probe was permanently failing. Switch to tcpSocket to match
the startup and liveness probes.
