This cannot fix everything
Sorry, I've been focusing on one thing at a time, starting with the things that I can fix my side.
Even though the underlying issue is with UI scaling, the Shattered Planet thing should be easily fixable by simply changing the label_orientation to something else. The default value of 0.25 is up and to the right, which is exactly in the direction of the next location, so simply rotating that around to 0.75 or something that is below and to the left instead, should keep it out of the way in all cases.
Guaranteed fixable by modders now > Potentially fixable by game devs later, imo.
And even if/when they do decide to fix the scaling issue, that doesn't make these changes any less useful
