Bug 30982: (QA follow-up) Remove redundancy from template

Bug 30982: (QA follow-up) Remove redundancy from template

The template now contains two lists for both status and type:
a TT list and a JS list. The type list already proves that
redundancy leads to bugs. We miss three types at one side:
    Unknown job type 'stage_marc_for_import'
    Unknown job type 'marc_import_commit_batch'
    Unknown job type 'marc_import_revert_batch'

This patch removes the TT list. And gets the status and type
via an additional js call. For that reason I hide the fieldset
until document ready. This can be improved later when needed.

Test plan:
Look at status and type on both job list and detail view.
