Hide ended statements in graphs by default

[ScatteredInk]

Example of current and former ownership and control relationships coexisting: https://register.openownership.org/entities/5b16a8b89dfc3fae18f62024/graph

In my experience the default behaviour of showing all relationships regardless of whether they have ended:

• is a source of confusion for users;
• gives the impression that the data is messier and less useful than it really is.

I would prefer to see only the current situation, with some mechanism to see past ownership positions.
