Moves the stretch to the bottom of the page to avoid awkward whitespace
in the middle. Presumably the totals used to be at the bottom (since
that's a normal place for a total), but it was moved to the top,
probably since that was the most interesting data and we didn't want to
scroll though all the details to find that one point.
This also removes the unused code path where the total would be shown at
the bottom.

It sounds like PySide2 will not be moving to Python 3.11, so we're stuck
on 3.10 without this. Upgrading to a newer Qt also fixes some high DPI
bugs (the file browser dialog for save/load is no longer tiny on 4k).
https://github.com/pyinstaller/pyinstaller/issues/5414 previously
blocked this, but the bug appears to be fixed now.
This appears to be incompatible with pyinstaller. I get the following
when trying to run the executable generated with pyside6:
```

Much of the UI was using the old budget which wasn't removed from Game
like it should have been when Coaltion was introduced. The UI displayed
(and in some cases pulled from) the starting budget rather than the real
budget.
This adds both player and enemy income multiplier options. Note that
previously the AI was only getting 75% of their income. I've changed
that to give them their full income by default since the player can now
influence it.
