Page not found - design

[MrrrrFox]

Problem description

Currently the design does not provide any view for "page not found" view.

TO-DOs

To design

• Prepare the design for the "page not found" view, e.g. when the URL is /test which not be in our routing
• Think, whether user should get another "page not found" view for the experiment, i.e. when the experiment with certain ID is not found (eg. expieriments/1 will be found but experiments/123123123 not), should user see the standard not found view (the one prepared from point above) or dedicated one with some sort of "experiment not found, ask admins..." text

To code

• Introduce the basic view for the page
• Improve the view according to the design
