add a playwright test testing the MediaManager / Referencing Posts functionality

Make picture-route return 200 / empty instead of crashing the server on pictures that do not exist

Started testing the media manager and implemented delete endpoint for pictures

Add a test testing adding of images. This cheats a bit in the ui, by setting diplay: inline to the invisible <input /> and commanding it, as doing dnd in playwright seems impossible and the <button> commanding an invisible <input type="file"/> is also a bit difficult. This, however, makes sure the media gets inserted into the db.

Added a 404 handling for @json routes that return nil

add a test for preview

add api route /api/posts/post/:id

add a test that makes sure the postview opens

a shitton of api fixes. The playwright tests pass currently on lisp server.

make editing a post to sort of kind of works but not really

add a playwright test testing that editing a post results in an edited post

implement GET /api/pictures/:guid and the endpoint powering "referencing posts" feature in the postmanager

make drag-and-dropping images to ace-editor work

add readme

add GET /api/posts/post and make editor able to create posts

add "GET /api/pictures/list/all" and make media manager load. Can't test it yet as the post editor probably doesn't work

make post manager load

make session -route return the logged in user

murja frontend loads :D

add a rudimentary lisp project structure that's loadable by ql/asdf

write an initial e2e-test around the old murja app
