[IMP] http_routing: make the 404 image use theme color

With this commit, the 404 image is now using the theme color.
Not only it will be displayed in the secondary color, but it will also gets
updated when the theme color is changed.

This one was waiting for the new editor to handle inline svg as regular img
(task-2497786) but in the meantime, the website is now capable of doing that
another way, as does in this commit.
