Each adapter now tags its Resources with a kind (vm, container, app,
host, network) so Node Status tiles show the right icon instead of a
generic server glyph — Proxmox LXCs/Docker containers get a container
icon, VMs get a VM icon, Uptime Kuma monitors get an app icon, etc.
Also stops silently swallowing listResources() failures — they're now
logged as warnings, since a connected-but-empty integration (e.g.
Uptime Kuma reporting zero monitors) was previously indistinguishable
from a real adapter error.
