fix: address CrazyWolf13 review feedback

- Add GitHub URL to source line (ct/plane.sh)
- Replace ${APP} with direct 'Plane' string in msg_* calls
- Use fetch_and_deploy_from_url for MinIO server download
- Add explicit 'tarball' mode to fetch_and_deploy_gh_release
- Use setup_uv + uv venv + uv pip instead of python3 venv
- Combine systemctl enable commands into single line
- Use ${PG_DB_USER} var in credentials output
- Merge MinIO bucket creation into service creation block
