The desktop node table used rowKey="id", but transitive sub-nodes (the
read-only rows surfaced from downstream nodes) all carry id 0, so a topology
with two or more transitive rows gave React duplicate keys. antd's rowKey
prop overrides the row object's own computed `key` (`t-${guid}` for
transitive rows, the numeric id otherwise), so the unique key the code
already builds was ignored — causing row-state/DOM mis-association on any
re-render (heartbeat refetch, address-eye toggle). The mobile card path
already keyed by record.key.
Key the table by "key" so transitive rows get their distinct t-${guid}
identity; direct nodes keep key === id, so row selection (filtered to numeric
keys) is unchanged.
