Show container/image opencontainer label information

[jelly]

It turns out that there is an opencontainer data standard which OCI images have which exports some useful information I want to make available in cockpit-podman for myself as it is generally useful and awesome. The information is:

                    "org.opencontainers.image.created": "2024-12-17T16:42:08.279Z",
                    "org.opencontainers.image.description": "High performance self-hosted photo and video management solution.",
                    "org.opencontainers.image.licenses": "AGPL-3.0",
                    "org.opencontainers.image.revision": "fd34a914a6b2e6dcfbbe53afcf0112cabccc232b",
                    "org.opencontainers.image.source": "https://github.com/immich-app/immich",
                    "org.opencontainers.image.title": "immich",
                    "org.opencontainers.image.url": "https://github.com/immich-app/immich",
                    "org.opencontainers.image.version": "v1.123.0"

Most notably I want to be able to see a Description, Documentation link, and version. A hacky version of this is shown here:

And could be also show in the existing details tab:

Here the Description is super useful, showing what the image is before potentially deleting it. A link to its docs can be useful as it might be helpful to figure out how to run this container.

I also want to have the Version, and maybe links? Shown in the container overview. When using the latest tag for images it is useful to be able to check if a quadlet was auto-updated by showing the image version metadata.

If you want to know what images have Labels:

podman images --format '{{.Names}} {{.Labels}}'

For me most of my applications have Labels set:

[docker.io/koenkk/zigbee2mqtt:latest] map[org.opencontainers.image.authors:Koen Kanters org.opencontainers.image.description:Zigbee to MQTT bridge using Zigbee-herdsman org.opencontainers.image.documentation:https://www.zigbee2mqtt.io/ org.opencontainers.image.source:https://github.com/Koenkk/zigbee2mqtt org.opencontainers.image.title:zigbee2mqtt org.opencontainers.image.url:https://github.com/Koenkk/zigbee2mqtt]
[docker.io/jellyfin/jellyfin:latest] map[org.opencontainers.image.description:The Free Software Media System org.opencontainers.image.documentation:https://jellyfin.org/docs/ org.opencontainers.image.source:https://github.com/jellyfin/jellyfin-packaging org.opencontainers.image.title:Jellyfin org.opencontainers.image.url:https://jellyfin.org org.opencontainers.image.version:10.10.0]

The labels are standarized here https://github.com/opencontainers/image-spec/blob/main/annotations.md#rules and just found out toolbox uses non-standard labels containers/toolbox#1046

[jelly]

Starting to think details makes tons more sense but we are a bit inconsistent with formatting in comparison with containers here:

So I would opt to consolidate the detail view of images into the same flex layout of containers. Leave out the akward metadata tab.

@garrett what do you think?
