Historic appointments

[SolviQorda]

• [x] View appointments should filter old appointments
• [x] new route for old appointments
• [x] build page
• [ ] filter function
• [ ] filter page

EDIT : I'm going to avoid filtering for now, as there is a stumbling block on the esqueleto queries. Going to put this on the back burner for now

Working compromise - change the datatype of filterchoice to be a date. Which will require some marshalling.

97 will be the issue for this going forward
