Replace old focus CSS for message-name/-type
Replace old focus CSS for message-name/-type

Template list items without checkboxes use the
`.message-name` and `.message-type` classes for
their links and hints.

This means styles used to expand the focus area
previously are clashing with the new approach.

This removes the old ones and gives
`.message-type` paragraphs a non-static position
to give them a z-position and so raise them above
the expanded link area.
