Add rough implementation of the lifecycle summary components.
This PR adds components for all the different lifecycle stages. We don't
have any data yet, so they're all hardcoded for now, just to get the
visuals right. I'm expecting the lines of code to drop and to
refactor/extract some structures as development continues.
For now, this is what they look like:

Things to note:
- The lifecycle stage icon colors don't match up with the sketches, but
they match up with what we currently have in the app. If we change them,
we should change them together.
- This implementation does not contain the "Flag lifecycle" header or
the "view graphs" link.
This change adds a few small bits of styling to the status modal to
get us going. It:
- adds padding to the whole modal
- adds a row for the health and resources widgets
- add project health placeholder
It leaves the project activity widget alone for now.
it makes the modal look like this:

This PR begins to stub out the project resources widget. I still need
one more piece of data and then to work on the styling, but it's a
placeholder for now. I've also moved the project status modal to its own
folder so we can group the widgets etc. I'd like to get that merged
quickly to avoid any future conflicts, which is why I'm making the PR
ready now.
