Switch OpenCloud to internal authentication mode

- Enable internal IDP service (remove from OC_EXCLUDE_RUN_SERVICES)
- Enable demo users (IDM_CREATE_DEMO_USERS=true)
- Enable basic auth (PROXY_ENABLE_BASIC_AUTH=true)
- Remove opencloud init command (not needed with ConfigMap)
- Remove conflicting admin user overrides

OpenCloud now uses internal user management instead of external OIDC.
Demo users will be created on first startup (admin, einstein, marie).
