podman suport, using podmans docker compatibility mode nearly works but crashes Overview and Containers pages

Describe the bug
Feature request/help me debug

Make dockerman work with podmans docker compatibility mode / help me debug.
Currently, most things work, but the Overview and Containers pages crash.

This would be awesome because podman works with nftables if you "manually" configure the network, and podman provides the possibility to run containers as none root user aka unprivileged containers.

What did I do to test this

1. Install podman according to this guide https://openwrt.org/docs/guide-user/virtualization/docker_host#podman
2. Don't worry about the configuration files, they get installed by the packages looking exactly like the example ones in the guide. Except for the ones that define a specific container.
3. Force remove the docker package with opkg remove docker --force-depends
4. Create a one-line shell scrip wrapper called docker in /usr/bin/docker according to this guide https://podman-desktop.io/docs/migrating-from-docker/emulating-docker-cli-with-podman.

#!/bin/sh
[ -e /etc/containers/nodocker ] || \
echo "Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.>
exec podman "$@"

7. Create a symbolic link from /var/run/docker.sock to /run/podman/podman.sock ln -s /var/run/docker.sock /run/podman/podman.sock
8. enable the podman service /etc/init.d/podman enable
9. If /var isn't persistent, add the symlink creation to your /etc/rc.local

/etc/rc.local
# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.

## Podman

# create podman docker emulation socket
ln -s /run/podman/podman.sock /var/run/docker.sock

...

10. reboot and test dockerman.

PS: I'm willing to create a proper podman-docker compatibility package for OpenWrt, but would like to get dockerman working first.

A few pictures:

Configuration page

Overview page

Containers page

Images page (no clue why it's broken now, it was working before)

Networks page

Volumes page

Event page

So as you can see it's kinda working but needs some attention.

My understanding is that it should be possible to get it to work, I will try, but this is my first adventure in to lua and in to luci, so I don't have the highest hopes.

Podman or more accurate netavark seems to be getting proper native nftables support soon, see containers/netavark#883

It seems that the podman compat api a little bit differently from Docker, will fix it later.
