scripts: remove hardcoded paths, clean up run.sh kill logic

- All scripts use \${HOME}/miniforge3/bin/python3 instead of /Users/uplab/...
- test.sh uses relative path to puppeteer dir (../../puppeteer)
- check_sdk.sh uses importlib.metadata instead of hardcoded pip path
- run.sh: kill only the previously saved port (from numzoo.port) instead
of scanning + force-killing all 7860-7865 ports
