(once https://jira.mongodb.org/browse/COMPASS-8133 is in)

"Connect" saves everything when adding a connection and only updates last used when editing a connection.

In multiple connections we get tripped up by using the edit connection form to change the favourite name and colour and then hitting connect, assuming it would save.

We can't just make the button save & connect because it would break the use case where some users save a connection without credentials and then edit it, fill in credentials and then connect. (Which would not save the credentials.)

This might be a happy middle ground because favourite name and colour should be safe to always save.
