This changes how initial searches can be handled via config rather than
specific action so they can be considered in how the initial data load
is done, to prevent the default empty state loading and overwriting the
search data if it lands later (which was commonly likely).
For #4778
- Split everything into specific plugin/concern files to make things
more managable. Means original component file is now simple and much
of the core config is focused in one place.
