remove Dockerfile, use stock python:3.12 image in Jenkins

- Delete custom Dockerfile (was ubuntu:24.04 based)
- Use Jenkins agent { docker } with stock python:3.12 image
- Remove apt/platform detection from setup.sh (python:3.12 has gcc, git, curl)
- Fix deprecated license format in pyproject.toml
- Use reuseNode to share workspace, chmod cleanup for root-owned files
