Note this commit also introduce a new {{d-popover}} component, example usage:
```hbs
{{#d-popover |state|}}
{{d-button label="foo.things" class="d-popover-trigger"}}
<div class="d-popover-content">
Some content
<div>
{{/d-popover}}
```
If you happen to mention someone with the wrong capitalization for that
person's username (e.g. `@sAm`), that incorrect capitalization would get
displayed on their user card.
This update will fix that by displaying the `user.username` value, which
will have the correct capitalization.
I also added some tests that will ensure `username` and `name` are
displayed on the user card in the correct order based on the
`prioritize_username_in_ux` setting.
This issue was reported here:

The values in Discourse dropdown menus only come from admin-defined strings, not unsanitised end-user input, so this lack of escaping was not exploitable.

* user preference to enable experimental sidebar
* `experimental_sidebar_enabled` attribute for current user

Before this change, we were using the labels from the original chartData to the chart builder, and we would then apply our collapse function on each dataset which could change the labels and cause a mismatch.
This was very visible when using quarterly periods on consolidated pageviews.
Other things may have added things to the style attribute (e.g. the `image-aspect-ratio` decorator).
Unfortunately this is difficult to add a test for because `lazy-load-images` leans on the `onload` event. We have no control over image loading in tests, so race conditions would be very likely.
- Make proxy pass `x-forward...` headers, so that Rails can set the host/port correctly in the csp
- Make `testem.js` available on a route which is within the app's default CSP
There was an edge when a user re-quoted a nested quote that it would return an incorrect `full name` but the correct `username` for the original quote. This PR updates the logic to fall back to using the OP user's username.
The complexity of the changes required to allow for full names to be displayed on nested quotes far outweighs how rare quoting nested quotes is.
