MC options default sorting and visible count changes

[cemreinanc]

The current state of things is:

• Feed tile lists, feed tile graphs, and question page graphs are always sorted by CP
  • except when the question is resolved, then the resolved option is always first
• Feed tile list options are capped to 3 (+other)
• Feed tile graph options are uncapped
• Question page options are capped to 3 (+other)
• The options are written in full independently of length.

We would prefer if

• The cap was 4 options +other everywhere: question page graphs, feed tile list, and feed tile graphs
  • except if the options are exactly 5, in which case show all 5 everywhere
• The selection was still based on CP + resolved everywhere, but
  • if the options are in a fixed order, then keep the relative order in the selected options everywhere
  • keep the order even if the question has been resolved
• The options were truncated if they are too long.

An additional thing we would prefer, but it's a bit niche and feel free to skip it if it makes things too complicated:

• Never order by the CP when one has the CP hidden or when the CP hasn't been revealed yet.

context from merged issue #3744 :

Show more options by default on multiple choice timelines
Currently we show only 3, which is way too few.

Example:

We should show 5 by default, with the legend wraping into several lines if necessary.

Also the popup should have the value of "others", so probabilities sum to 100%.

context from merged issue #3668 :

Show all (or at least more than three) multiple choice choices when they are toggled on

Right now, if I've toggled on more than the default 3 visible multiple-choice options, such that they're visible on the graph, I can only see their names/color assignments by expanding the other dropdown. This is kind of annoying and unintuitive, and it often takes me some nontrivial number of seconds to realize that I need to re-expand it to figure out what the newly added colors mean. It seems like we have space for at least several more, and possibly many more.

Feature description
It seems optimal to me that up to some fairly high cutoff (whatever multiple-choice options are toggled on), more MC options should be visible immediately below the plot, even if we have to dynamically expand that area to fit multiple rows of them. Obviously, there should be some cutoff for extreme outlier multiple-choice questions with more than something like 10-15 options, but these are pretty rare, and we can set an option that would make the UI more intuitive for the vast majority of multiple-choice questions.
