### Summary
🎨🐛🚀

<!--
1. 🎨 - This emoji is often used to indicate code style or formatting
improvements, such as refactoring, renaming, or reorganizing code. In
this case, the `DropdownMenu` component was refactored to improve code
readability and consistency, which could be considered a style
improvement.
2. 🐛 - This emoji is often used to indicate bug fixes or error handling,
such as fixing a missing closing tag, a typo, or a logic error. In this
case, the `DropdownMenu` component had a missing closing tag for the
`ul` element, which could cause rendering issues or invalid HTML, so
fixing it could be considered a bug fix.
3. 🚀 - This emoji is often used to indicate performance improvements or
new features, such as adding a new component, a new functionality, or a
new optimization. In this case, the `DropdownMenu` component added a
`Flex` component to align the menu items, which could be considered a
new feature or a UI enhancement.
-->
Refactored the `DropdownMenu` component and fixed a bug in
`packages/uikit`.

> _The `DropdownMenu` was a mess_
> _With a tag that it failed to address_
> _So it got a refactor_
> _And a `Flex` benefactor_
> _Now it looks and behaves with finesse_

### Walkthrough
* Reorder imports alphabetically and move `LinkStatus` component up to
match styles file

* Wrap `MenuItemContent` in `Flex` component to align label and status
horizontally and add closing tag

* Replace `label` prop with `MenuItemContent` variable to reuse
rendering logic
