[WIP] 🔧(dev) make the dev stack work with rootless podman

Rootless podman maps container UID 0 to the host user and every other
container UID to a subuid that owns nothing in the worktree, so the usual
DOCKER_USER=$(id -u):$(id -g) makes every bind mount effectively
read-only.

Pin the LiveKit rtc section: the browser reaches the server through
podman's published ports on loopback while egress and the agents reach
it over the podman network, and those two have no address in common.
`advertise_internal_ip` keeps the container's own interface address as a
host candidate alongside the node_ip one, so LiveKit offers both and ICE
picks whichever works. Without it egress only ever sees 127.0.0.1, which
is the egress container itself, and its peer connection timeouts

Prerequisite on the host: systemctl --user enable --now podman.socket
