fix(agent-team): don't render build/verify/dispatch as 'inert'

The backend still flags the P3 nodes (build/verify/dispatch) gated:true, but in
the live R720 deployment they are wired and active — so that flag is a stale
'P3 opt-in' hint, not a real 'inactive' signal. Stop deriving the dimmed/'inert'
treatment from stage.gated / meta.gated in both the Board columns and the DAG
nodes; activity is conveyed by live task counts + status colors. Human gates are
unaffected (still keyed off topology kind 'gate').

Typecheck + 36 tests + build all green.
