fix(central-ui): Flow Debugger spawn edges — real arrowhead + bolt badge; spawner picked by trigger attribute

Browse Source 
The trigger-cascade (Spawn) edge used a lightning-bolt marker IN PLACE of the arrowhead. On the upward
Tags→Site hop the bolt sat on top of the riser and read as a broken arrow (rig screenshot 2026-09-08).
Every connector now ends in an ordinary arrowhead; the bolt is a badge (circle + bolt) centred on the
connector's vertical run (FlowGraphView.SpawnBadgePoint, kept in step with OrthogonalPath/AsyncPath).

Same screenshot, second defect: the cascade spawned by "RecipeDownloadFlag = false" was drawn from the
LAST write of the burst (RecipeProcessedFlag) because all four writes share a millisecond and the
spawner rule was time-only. FlowGraphBuilder now prefers the parent's last AttributeWrite of the attribute
the child's triggerAttribute names (at or before the child, else the last such write); the time/position
rules remain the fallback when the child names no attribute or the parent never wrote it.

Verified live on the rebuilt rig (DelmiaSim01 / DelmiaReceiverSimulator): both spawn edges show an
arrowhead + badge, the second one originates from the RecipeDownloadFlag write. bUnit + builder tests
updated/added; Playwright FlowDebuggerTests 4/4.
