Market Price - Improvements

Window should come into foreground when it is opened/a new item is added

The comparison feature should be explicitly invoked, not automatically trigger when a new market value is selected. (Why? In most cases I am trying to check unrelated items, maybe add a “Compare Price…” context menu option to use this feature. A toggle to have it work implicitly like currently could allow for the user to opt-in rather than change the existing flow for many)
