Rename property from `params` to `unusedParams` for clarity.

Change the way that links pointing into the Hypothesis service (eg. for
tags, users, account settings etc.) are fetched and generated. The new
implementation better matches patterns used elsewhere in the application
and ensures that UI components displaying these links re-render if the
`/api/links` response is received after the component is initially
rendered.

 - Move the logic for rendering the URL templates from the `serviceUrl`
   service into a selector in the `links` store module. Components then
   render links using `store.getLink(...)`. This ensures use of the existing
   mechanism that re-renders components when relevant store data changes.

 - Convert the `serviceUrl` service to an ES class

 - Move the logic for fetching URL templates from the `/api/links`
   endpoint into an `init` method of the `ServiceURLService` service.
   This matches the convention used by several other services.

 - Remove unused `serviceUrl` dependency from `groups` service

As noted in a comment, the check is mainly intended to prevent infinite
loops in tests.

The name options implies a misc bag of optional properties, whereas this
is a mandatory set of callbacks.

This found a mistake in the types of several references to the document
URI, which is not always present.

This found an error in some of the existing types in the `api` service.

Refactor this class to new conventions as part of
https://github.com/hypothesis/client/issues/3298.

 - Convert the `auth` service to an ES class
 - Replace the internal `emitter` variable with inheritance
 - Rename the module from `oauth-auth.js` to just `auth.js`. The
   previous name is a vestige from when authorization was migrated from
   cookie-based to OAuth-based

 - Convert `features` service to a class

 - Remove the unused `flagEnabled` method. Calls to this method have
   gradually been replaced by `store.isFeatureEnabled`.

 - Move the initialization of the background sidebar => annotator
   synchronization of feature flag information into an `init` method
   which is then called from the sidebar's entry point. This pattern is
   consistent with several other services. It is also necessary for services
   that are not depended upon by anything else because services are
   lazily instantiated.

Put all the initialization logic in one place instead of spreading it
between the constructor and `init` method.

This conversion revealed some incorrect and inconsistent types.

- The `filter` method was documented to return `Tag`s but actually
  returned strings
- The `store` method required a list of `Tag`s but only used the `text`
  property from it. This method has been simplified to just accept a
  list of tag strings instead.

In the process an issue was uncovered where an annotation could
incorrectly be created without a group if there was no focused group.
Address the issue by throwing an error in `AnnotationsService#create` if
there is no focused group. Handling the situation in a
context-appropriate way is left an exercise for higher-level code.

Convert `localStorage` class to an ES class and add types to various
places where it is referenced.

Instead, use SASS from `frontend-shared` package

These shared button components have been moved to the `frontend-shared`
package.

Update `StreamFilter` class to current service conventions. Part of
https://github.com/hypothesis/client/issues/3298.

Mock `retryPromiseOperation` in APIRoutesService tests to speed up tests
where the operation is retried multiple times.

The customized result for the first stub call was not used because a
more specific response was defined earlier using `withArgs`.

Follow the pattern introduced in https://github.com/hypothesis/client/pull/3296
to convert the API routes service to a class and improve various types
along the way.

The only way to kill `yarn test --watch` is sending a SIGINT via a
<kbd>Ctrl</kbd>+<kbd>C</kbd> keyboard shorcut. Killing karma process in
this way sometimes leaves the parent gulp process orphan. That's because
when karma is killed by SIGINT sometimes doesn't run the `done` in the
callback, hence leaving the gulp process waiting for the `done` signal.

On more rare occasions, I have seen orphan karma process too.

The solution presented here registers a listener for SIGINT and call the
`done` function. It doesn't unregister the event.

Add tests for logic in Guest related to focusing/selecting annotation cards
in the sidebar when the corresponding highlights in the document are
hovered.

Previously there were three public methods for setting the selected annotations
in the sidebar and opening it, but only one was used outside of `Guest`
and there was an inconsistency when toggling vs selecting normally.

 - Combine the `showAnnotations`, `toggleAnnotationSelection` and
   `selectAnnotations` method into a single `selectAnnotations` method
   with a `toggle` parameter

 - Add tests for `selectAnnotations`

 - Fix an inconsistency where selecting an annotation without holding
   Ctrl to toggle the selection would open the sidebar, but selecting an
   annotation with Ctrl to toggle the selection did not

Give this method a name that more obviously explains what it does.

Make the distinction between the private and public API for Guest
clearer by marking private fields clearly.

 - Convert toastMessenger service to an ES class using a named export
 - Specify type of `toastMessenger` references to this service

Change loadServiceSpecifiedGroups() so that it can pass along an optional group ID setting value from the `directLinkedGroupId` selector to be an initially focused group.

When loading groups from a service e.g. `loadServiceSpecifiedGroups`, previously it assumed that the `directLinkedGroupId` value would never be used in this context. Since the introduction of the Notebook and specifically in the context of LMS, we have both a service setting which contains the groups  (`settings.services[0].groups <Promise>`) and a top level group to set focus too. (`settings.group`).

Set a Z-index that is sufficient to make the dialog appear on top of
other content in the sidebar, mainly the top bar. We will likely have to
revise this if `confirm` is used in other contexts in future.

Convert existing uses of `window.confirm` to use our own `confirm`
utility which uses the standard Dialog from our pattern library.

Using our own prompt avoids an immediate problem that browsers, starting
with Chrome v91, are starting to block the use of `window.confirm` in
third-party iframe. It also makes the visual design of the prompt match
the rest of the application.
