feat: Show if binding is system or not in list

[sontek]

what

Expose if a binding is a system binding (stacklets) so its more obvious which ones are custom bindings.

why

I wanted to run a one liner that re-deploys all bindings but there was no way to filter out the system ones before. With this change I can do this:

  uv run stacklet-admin --output json binding list | jq -r '.data.bindings.edges[] | select(.node.system == false) | .node.uuid' | xargs -P 4 -I BINDING_ID uv run stacklet-admin binding deploy --uuid BINDING_ID

testing

I ran this against my sandbox:

uv run stacklet-admin --output json binding list | jq -r '.data.bindings.edges[] | select(.node.system == false) | .node.uuid' | xargs -P 4 -I BINDING_ID uv run stacklet-admin binding deploy --uuid BINDING_ID
