* On the "Certification Required" error page: show help text under the
checklist to make it clear that clicking the checklist item will link
to the profile photo or cert photo upload page.
* Add more helpful text around the site to address common confusion:
* On the Photo Upload page for profile_pic and the user is already at
quota: add special text saying they can use an existing gallery
photo as their profile pic instead.
* On the self Gallery view page: if the user has no profile pic
currently set, offer advice and links on how to set one.
* Fix the image max-width on Gallery lightbox modals
