Facia cards 2.0

First container under new container regime:

1. `fc-` prefix keeps new code separate from incumbent containers. adds temporary bloat but means the old stuff can be safely retired at a later date
2. presentation logic has been moved from templates/css into new slice scala modelling 

todo:
- remove old `standard`/`list` templates into single `item` template
- large media list (50% image width)
yeah i think so - it’s easy enough to get back to now from this conversation :smile: I’ll nuke it
