Move the new-project form into the dashboard grid as a tile

It now sits last in .dashboard__grid, styled like a project-card (dashed
border to read as an action rather than a project) instead of as a
separate form below the grid. Relabel it 'Create a project' and add a
'Name' placeholder to the input.

Also drop the now-redundant 'no projects yet' empty-state message --
the grid always renders since the create tile lives inside it.
