[DYN-7845] Hide input and output ports from collapsed groups

[ivaylo-matov]

Purpose

This PR aims to address DYN-7845.

New Preference Settings:

• added options to hide optional input ports and unconnected output ports by default when a group is collapsed
• added a preference to automatically apply minimum width and height to collapsed groups

Port Toggles:

• collapsed groups now display toggle buttons that let users manually expand or collapse optional input ports and unconnected output ports per group. Optional input ports are the disconnected input ports that use default values, unconnected output ports are output ports with no outgoing connections.

Manual Overrides:

• once a group’s ports have been manually toggled via the UI, the group will no longer respond to changes in the corresponding global preferences

Please note that to calculate the minimal width of a collapsed group, the view waits until the ports have been rendered once, then reads their measured DesiredSize to compute the smallest area needed to fit all visible ports and toggles. This causes a second render pass for the group .
