Clicking a service tag selects it (stops node drag), extends Selection
discriminant with {type:'service',id,nodeId}, and renders an inspector
panel showing proto/port/subnet/risk chip + REMOVE SERVICE button
(gated off for observed nodes and degraded topologies). Service-tag
styling now pulls `risk` from DEFAULT_SERVICES metadata instead of
node.status alone.
Rebuild the inspector panel to match the handoff mock: crosshair-titled
header with dim type label and close X, status-dot + archetype-chip
head rows, connection list with directional arrows, member list with
click-to-select, and a pending-diff block at the foot. Carry the
gateway/observed disable titles over from the ctx menu so the 'remove'
action stays honest.
Also prefix the subtitle with 'NETWORK OF NETWORKS' so the purpose of
this editor reads at a glance.
