Replace Docker with Podman throughout
- builder/build.sh: all docker commands → podman (build, run, stop, rm,
network create, images, rmi, inspect)
- server/src/routes/apps.rs: docker stop/restart → podman
- server/src/routes/ui.rs: docker inspect → podman
- infra/Dockerfile.server: install podman instead of docker.io
- infra/docker-compose.yml: rename docker-proxy → podman-proxy, mount
/run/podman/podman.sock (rootful Podman socket), update DOCKER_HOST
- infra/Makefile: docker compose → podman compose
Podman is daemonless and rootless by default; OCI images are identical so
no build-pipeline changes are needed beyond renaming the CLI.
