* web: fix Flash of Unstructured Content while SearchSelect is loading from the backend
Provide an alternative, readonly, disabled, unindexed input object with the text "Loading...", to be
replaced with the _real_ input element after the content is loaded.
This provides the correct appearance and spacing so the content doesn't jiggle about between the
start of loading and the SearchSelect element being finalized. It was visually distracting and
unappealing.
* web: comment on state management in API layer, move file to point to correct component under test.
* web: test for flash of unstructured content
- Add a unit test to ensure the "Loading..." element is displayed correctly before data arrives
- Demo how to mock a `fetchObjects()` call in testing. Very cool.
- Make distinguishing rule sets for code, tests, and scripts in nightmare mode
- In SearchSelect, Move the `styles()` declaration to the top of the class for consistency.
- To test for the FLOUC issue in SearchSelect.
This is both an exercise in mocking @beryju's `fetchObjects()` protocol, and shows how we can unit
test generic components that render API objects.
