[Feature] Add sortable list of all tests in database

Hi,

it would be nice to have a list of all the tests in the database, so you can sort them for their sensibility and then decide which one to buy.

Last time I used this list: https://datawrapper.dwcdn.net/zoI2k/3/

But it would be much nicer if it would be available on a more meaningful Domain like schnelltesttest.de
