Add Collapsed pin display mode with a 3-dot state icon

Browse Source 
Cycle each node through All -> Connected -> Collapsed -> All via a
custom-drawn icon (filled-dot count encodes how much is shown: 3/2/1).
Collapsed hides every pin on a side, linked or not, behind one
connector nub; existing links now redirect to that nub too
(EffectivePinId), so they visually converge like Hypershade's collapse
view instead of only hiding unconnected pins. Also moved the connector
nubs off the title row onto the node's bottom row. Persisted mode
switches from a bool (uiShowAllPins) to an int (uiPinDisplayMode).
