- `props.innerRef` in `<IFrame>` was inadvertently assumed to always exist, sometimes throwing an error on render when certain popups like the profile settings modal were opened resulting in the app crashing and the whole comments block disappearing
- added a guard to ensure the ref exists before trying to set it
- updated tests so the profile modal route is tested

Comments-UI loads `/ghost/admin-frame/` in an iframe to check if a Staff User is authenticated in order to show moderation options. That iframe request loads a HTML page which in turn contains a script that fires off an API request that attempts to fetch the logged-in user details, resulting in a 403 "error" showing up when not authenticated. In the vast majority of cases there will be no staff user authenticated so lots of extra requests and "errors" are seen unnecessarily.
- adjusted the `/ghost/auth-frame/` endpoint to check if the request contains an Admin session cookie
- if it does, continue as before with rendering the HTML page so the script is loaded
- if it doesn't, return an empty 204 response avoiding the script request and subsequent 403-generating API request
- eliminates the 403 error being generated for all typical visitor traffic, the error should only be seen when an Admin was previously logged in but their cookie is no longer valid (either from logging out, or going past the 6month validity period)

When an Admin is authenticated in Comments-UI we only add moderation options to the displayed comments so we don't need to pre-emptively load the `admin-auth` iframe and make the `/ghost/api/admin/users/me/` request until some comments are actually visible.
- used `state.comments.length` property to defer rendering of the admin auth frame until comments have been fetched (after box is scrolled into view) and the count is > 0

Now we have the case that there is no filter param, the simple string
approach fails. Instead we build up a URLSearchParams object which
makes it easier to handle conditional params & stringify it at the end.

The comments block is typically shown at the bottom of a post so it doesn't make sense to eagerly fetch comments from the API when we don't know if the comments block will even be viewed. By lazy-loading the data only when the comments block comes into view we can reduce both data usage for visitors and load on the site.
- uses IntersectionObserver API to delay comments app initialisation until the comments block has scrolled into view
- updated all iframe-related components to forward a `ref` so we can use the `<iframe>` element reference inside the `App` component

- App component now uses React hooks intead of React class component
- App is now written in TypeScript
- All JavaScript is now removed from the Comments-UI project
- Removed `PopupNotification` because these were never displayed
- Removed `action` from AppContext (never used)
- Moved options parsing out of `index.ts` into a separate utility file,
similar to the signup-form
- Improved reliability of some editor tests by always waiting for the
editor to be focused (was not always the case) + added an utility method
for this

- When you are logged in as an admin, but not as a member, no buttons
showed (discovered in new e2e tests)
- Added E2E tests for admin actions

This migrates comments-ui to TypeScript. Only `App.js` is left to
migrate, but since this isn't using hooks yet, it will need a bigger
rewrite so this will need to happen in a separate PR.
