fix: move panel height correction from loadWorkflow into BaseNode render

The pre-subtraction in loadWorkflow was overridden by React Flow's
dimension reconciliation. Instead, correct at the source: in BaseNode's
expand timeout, read _settingsPanelHeight from node data and only add
the delta (measured - saved) so reloaded nodes don't double-count.
Also clear _settingsPanelHeight on collapse to avoid stale values.
