feat: fix OIDC auth flow, improve config dialogs, add mock IdP

- Fix OIDC callback to extract email from ID token claims as fallback
- Add /auth/complete bridge page to transfer auth to NiceGUI storage
- Use window.location.href for OIDC login (full navigation for OAuth)
- Hide password change card for OIDC-only users
- Widen config dialog, use ui.code with syntax highlighting
- Switch QR codes to PNG base64 images
- Rename logging.py to log_config.py to avoid stdlib shadow
- Add mock-oauth2-server to compose.yml for dev/testing
