links have different behavior than Obsidian

[l3enQ]

** User Story **
as an end user, I want to fix some link issue so I can feel exactly like the Obsidian.

Describe the bug
links have different behavior than Obsidian.

To Reproduce
1- when you press a link port a temp connection immediately created
2- temp connection is above the nodes in z value
3- temp connection is not snapped to the destination port when is near
4- when temp connection is released in empty space and the objects node is shown, mouse movement moves the connection

Acceptance criteria

• 1- the temp connection should be created only if the user moved the mouse after press
• 2- temp connection should be below the nodes in z value
• 3- temp connection should be snapped to the destination port when is near
• 4- when temp connection is released in empty space and the objects node is shown, mouse movement should not move the connection and just can affect the object menu
