Add diabetes review cards to planner
Add diabetes review cards to planner

Rejig how we're building the list. We're still using query parameters to
work out the state, but now add the cards in one at a time.

This avoids having to enumerate all the possible list combinations based
on the query string.

Once we allow not-hardcoded appointments to be booked, the ordering will
probably end up horribly wrong. Classifying that as a problem for
another commit.
