Add Want to Read dropper to lists

[sbwhitt]

Closes #8206

Adds the Want to Read dropper to book options within lists.

Technical

Testing

1. Go to a list with books added.
2. The Want to Read dropper should display underneath the existing Read/Listen button.
3. Selecting the dropper when logged out should redirect the user to the login page.
4. Selecting options from the dropper while logged in should update the user's reading log as expected.

Sorry for the delay. This looks good to me.
Noting that the list dropper doesn't appear for authors and subjects, but that's probably fine for now. Will open an issue about this if it becomes a problem.

No worries, thanks for reviewing. For the author page I opened this issue: #8520

Thanks for opening that issue and adding an assignee.
