openhands 4aa021a511 feat: switch default base image to nikolaik slim variant ...

Switch the default base container image from nikolaik/python-nodejs:python3.12-nodejs22
to nikolaik/python-nodejs:python3.12-nodejs22-slim.

Benefits:
- ~500 MB smaller image size on disk (16% reduction)
- ~62% smaller compressed size for faster downloads
- Faster Kubernetes node autoscaling due to reduced pull times
- Full functional parity with the non-slim variant

The slim variant is based on Debian slim, which removes non-essential
packages while maintaining all functionality needed for OpenHands runtime.

Files updated:
- openhands/core/config/sandbox_config.py: Default base image
- openhands/runtime/utils/runtime_build.py: CLI default
- .github/workflows/ghcr-build.yml: CI/CD builds
- config.template.toml: Documentation
- tests/*: Test assertions
