Add "Confirm user" button to admin page

### What does this MR do?

This MR adds a "Confirm user" to the admin user page.

### Why was this MR needed?

There is no way for an admin to force a user confirmation. Some users create users in the API and then don't have a way to force the user into a confirmed state.

Originally, I attempted to add a link to allow the admin to resend a confirmation e-mail. But that may not be helpful because a user can be in the unconfirmed state with no `unconfirmed_email` set.

Re-annotate models

Make `code` elements in links display as such

When a link consisted only of an inline code block -- ```[`like this`](https://google.com/)``` -- it was hard to tell that it was even a link.

Fix multi-line syntax highlighting

### What does this MR do?

This MR fixes multi-line syntax highlighting in the code views. HTML span elements only apply to a single line, and in the case of multi-line comments, the highlighting was dropped as a result. Ensure that each line has
the proper styling to fix this.

### Why was this MR needed?

The current styling was broken for a while.
