fix(container): activate podman socket on Linux when not running

[bmahabirbu]

Summary

• On Linux, the podman API socket is not always active — it requires systemd socket activation or Podman Desktop to be running
• Modified PodmanSocketLinuxFinder to spawn podman system service --time=0 when the rootless socket is missing, matching Podman Desktop's behavior
• The spawned process is killed on extension deactivation via @preDestroy() dispose
• Includes Flatpak support (flatpak-spawn --host)

Test plan

• Unit tests updated and passing (11 tests)
• On Linux without Podman Desktop running, verify Kaiden discovers podman containers
• Verify socket process is cleaned up when Kaiden exits
• Verify no duplicate process spawned on repeated socket finder polls

I'm questioning the rationale as we don't have this in Podman Desktop as ask user to run it so might have permissions issues. @benoitf might help

[jeffmaury]

praise: should use exec from the extension API

[bmahabirbu]

@jeffmaury I noticed that in podman-desktop the socket opens and closes automatically on linux so thought id just try to add the functionality in kaiden too

[benoitf]

so I know in Podman Desktop we start the service but users are complaining that sometimes they have the service already started so there are like 2 servers then

[benoitf]

overall I'm ok as it simplifies the default experience but as @jeffmaury said, it needs to use the exec API

[MarsKubeX]

Looks good in general but same comment as the others, use exec from the api extension

[benoitf]

@bmahabirbu are you planning to fix this ? or we put the label 'on hold'

[benoitf]

setting to draft as I didn't get a reply
