Speed up large imports by allowing up to 5 imports to be in-flight concurrently.
The simplest approach to this would be to divide the annotations into batches
and save one at a time. However due to the variability in the time that an
individual import can take, this can lead to sub-optimal concurrency. Instead
structure the code so that we try to always keep `MAX_CONCURRENT_IMPORTS`
imports in flight at once, as long as there are that many remaining.

Fixes https://github.com/hypothesis/client/issues/5739

This ensures that the count of annotations displayed in the Export tab matches
the count of top-level annotations that we show in the user list, and actually
import, in the Import tab.

When reporting unsaved annotations, use the term "draft" which covers both
annotations and replies.

Part of https://github.com/hypothesis/client/issues/5742

Simplify test to just check the essential `<details>`-related behavior compared
to other tests.

In the initial implementation of import, we have decided to exclude replies to
simplify the feature. In other words, the import feature only supports importing
top level annotations from a single user.

Extract the reading and parsing of Hypothesis JSON files out of the
ImportAnnotations component and into a separate module. This allows for it to be
more directly tested, and also may help to fix test flakiness in
ImportAnnotations by replacing the file "reading" with a fake that takes a more
deterministic amount of time (one tick).

May fix https://github.com/hypothesis/client/issues/5746.
