Replace `ActionButton`, `IconButton` components with `Button`

Converge button components into a single `Button` component and adjust
across various components accordingly. Refactor SASS for sanity.

Remove analytics tracking from annotation component

We are not actively doing anything with this data, so we can save
ourselves some Angular => Preact porting effort by removing the tracking
code for the time being.

These have been replaced by the new `TagEditor` component.

Use the `form-input` and `form-input-focus` mixins as the basis for all
input fields in the sidebar. This removes some duplicated SASS and
ensures that all input fields provide affordances look and behave a
little more consistently.

 - Move `:focus` and `@media (pointer: coarse)` adjustments for form
   inputs that were duplicated in several places into the `form-input` mixin
 - Change the `MarkdownEditor` and `SearchInput` components to re-use
   the `form-input` mixin for their input fields
 - Remove the unused `form-textarea` class

The end-user visible results of this are:

 - The search input in the top bar now looks consistent with other
   inputs when focused
 - The input field in the share dialogs now use a larger font size on
   mobile devices, which should avoid iOS zooming in when they are
   focused

Match other input fields in the sidebar in using a larger font size for
the tag editor input on mobile/touch inputs. This also prevents iOS
Safari from zooming into the input when focused.

Add new preact tag editor component

Add and use new `IconButton` component

Add and use new `ActionButton` component

No longer needed after `IconButton` added

- Eliminate custom sub-components that fulfill the same task
- Replace `AnnotationActionButton` with `IconButton` where used
- Consolidate and adjust styling
