fix(jobs): drop display_name override on workflow state — pills showed 'Name [code]'

The compute appended '[code]' so admin pages could disambiguate
states at a glance. But display_name is what the status-bar widget
uses to render each pill, so every pill came out as 'Received
[received]', 'In Progress [in_progress]', etc.

Removed the compute. Admin list view already shows code as a
separate column.
