Add artifact upload and improve apt-cacher-ng statistics

- Add upload-artifacts step to make packages downloadable from Forgejo
- Fix apt-cacher-ng statistics check to use correct port (3142 instead of 3143)
- Check both 192.168.1.101:3142 and localhost:3142 for statistics
- Add better messaging when apt-cacher-ng stats are not available

This completes the CI/CD pipeline with downloadable artifacts!
