Bug 32600: Housebound module needs page-section treatment

Bug 32600: Housebound module needs page-section treatment

This patch adds a .page-section container to two areas in the patron
homebound template.

This patch contains indentation changes, so please ignore whitespace
when looking at the diff.

To test, apply the patch and make sure the HouseboundModule system
preference is enabled.

- Locate a patron and edit their record.
- In the "Housebound roles" section, check both "Chooser" and
  "Deliverer."
- Locate another patron and click on the "Housebound" menu item in the
  left-hand sidebar.
- On the "Manage housebound profile" page, set a delivery day and
  frequency and save changes.
- On the "Housebound details for..." page the details section at the top
  should be correctly styled.
- Click "Add a new delivery."
- Fill out some delivery details and click "Save."
- Now the "Housebound details for..." page should show a "Deliveries"
  section which is correctly styled.
