Realign inspector breakout panel to come from left

This is a first step. The changes here break some of the ideas of the
viewlet-manager and viewlets. There are work arounds in place here so that we
can move forward and discuss how to adjust to the requirements here.

- Updates the unit and service details to come into the same space as charm
details.
- Works around the issue of the close event not being in the same dom tree as
the viewlet-manager and not caught to close the breakout panels.
- Updates the css for the new location.

- make devel
- view the site with :flags:/il
- deploy a service and once it's deployed, click on the "Charm details" link and
  a functional details popout should appear.
- Close and verify it closes properly and reopens as well.
- Go to a running unit and select the unit to open its details.
- Verify you can go straight from a unit to a service details and back/forth
  without issue.
- Verify that with a panel open, if you close the inspector the panel also
  closes.
- Verify that the inspector and panels work without the feature flag as
  expected.
