Add carried-over jobs section to Daily Board and fix tip visibility

Non-terminal jobs scheduled for past dates now appear in a red 'Carried
Over' section at the top of today's board so they can't silently disappear.
Also added alert-permanent to the board tip so the layout doesn't auto-dismiss it.
