Enable typechecking for sidebar/store/modules

Disable `_separate_replies` for annotation loading in sidebar (behind feature flag)

Typecheck UI components in src/annotator/components

- Add JSDoc for the `actionTypes` function. This uses an advanced
  TS feature called "mapped types" [1] to specify that the result is an
  object with the same keys as the input object, but where the values
  are strings rather than functions.

  Going forwards there are likely better ways to replace `actionTypes`.
  The original purpose was to make sure that the `type` field of each action
  object matches up with a key of the `updates` object.

- Fix various existing JSDoc errors
- Add imports for the existing `Group` and `Annotation` references
- Add missing `group` property to `Annotation` type

[1] https://www.typescriptlang.org/docs/handbook/advanced-types.html#mapped-types
    (See in particular the `in keyof T` mentions).

When associated feature flag is set, `_separate_replies` will be set
to `false` when loading annotations in the sidebar.

This follows the same pattern that was introduced for `SvgIcon` in
`propTypes` declarations are kept around for use at runtime by other
code which is not yet typechecked.

An issue that I encountered is that TS doesn't know about the custom
HTML element types we use. For the moment I have ignored these with
`@ts-ignore`, although I believe it should be possible to teach it.

Typecheck SvgIcon

 - Remove a param comment that duplicates information in the type
   definition
 - Add a note about a defensive null-check

Adjust the scale of layout spacing

Refactor annotation publish control styling

Typecheck `shared/components/svg-icon.js`. This enables edit-time rather than
runtime detection of incorrect usage, as well as enabling UI component
props to reference types (eg. API objects) defined elsewhere with JSDoc.

Props are currently declared with both JSDoc and via
`SvgIcon.propTypes`. The intent is that the JSDoc is the canonical
definition, but `SvgIcon.propTypes` is still useful to catch incorrect
usage from other parts of the code which are currently not typechecked.

Typecheck src/sidebar/services

As suggested in PR feedback, this can help readability. We should do the
same in parameter lists as well.

Change `margin` SASS var names for clarity

Refactor styling of VersionInfo and related HelpPanel components

Refactor VersionInfo's styling to be a narrow-first responsive layout
so that it is readable when the sidebar is narrow.

Enable minimal typechecking for src/sidebar/services. Note that most
service factories are missing parameter documentation, so their usage is
not checked.

 - Fix up JSDoc errors and omissions in `src/sidebar/services`
 - Add types for the `tiny-emitter` npm module. The module does ship
   with its own types, but doesn't specify the types for the default
   export
 - Add additional properties to `Annotation`, `Group` and `Profile` API objects

Typecheck `src/annotator/{config, util}` and `src/sidebar/*.js`

Simplify `since:<time>` filter query parsing and remove `result:<term>` parsing

Enable typechecking for the following directories:

 - src/annotator/config
 - src/annotator/util
 - src/sidebar (excluding `ga.js`, `icons.js` and `index.js`)

Many functions in these directories are still not annotated, but this
will be added over time. `ga.js` was excluded because it deals with
globals added by Google Analytics. `icons.js` was excluded because TS
doesn't know how to handle `require('.../some-icon.svg')`. `index.js`
was excluded because that imports (and thus triggers checking for) every
other file in the sidebar app. It will need to be enabled last.

There were no tests for this and this field is not used in the code that
consumes the output of filter query parsing (`view-filter.js` and
`stream-filter.js`).

Don’t hide the component when `store.isLoading()` is true. This only causes a re-render of that component and momentarily removes it from the DOM. Its not actually invalid to show the filter buttons while loading because the filter is still being applied.
