Organisation dashboard: Content and design fixes

[CharliePatterson]

Organisation dashboard

• [x] Org name in breadcrumb needs correct capitalisation
• [x] Dataset list should be alphabetically ordered
• [x] "Not submitted" tag should be grey
• [ ] "Live" tag shows alongside text showing issues exist / either the tag or the text is wrong
• [x] When there's only a single issue the text should be "There is 1 issue in this dataset"

Regarding:

 "Live" tag shows alongside text showing issues exist / either the tag or the text is wrong

This is the logic that sets the status:

   when (rle.status is null) then 'Not Submitted'
      when (rle.status != '200') then 'Error'
      when (it.severity = 'error') then 'Needs fixing'
      when (it.severity = 'warning') then 'Warning'
      else 'Live'

So if it has a status of200 and has no severity then it's Live.

@CharliePatterson - should we change this logic?
