Follow-up on #20296, #20311, #20301.
Updating `InteractiveLPProblem` to:
- use the standard-form transformation,
- simplify its code slightly by making use of the new
`objective_constant_term` handling in `InteractiveLPProblem`
- make the example of optimizing over the dodecahedron more natural and
remove use of backend methods.
- change default `base_ring` to QQ -- a much saner default because it's
so much faster

Comment (by mkoeppe):
Rebased on top of 7.2.beta4, which merged #20415.
Made the change to a better (much faster) default `base_ring` QQ.
Needs review.
