Enhance batch proposal status info

[JonRay15]

The Chore

It seems that we need to be a bit more sophisticated in how we deal with the final status of batch proposals.

The issue is that in some cases like the image below the overall batch can pass - because the vote was successful - but then some parts of the batch can fail in the execution step.

In these cases the core status will remain on STATE_PASSED because the overall batch has indeed PASSED ... but if we just show this alone in the governance app it is quite misleading to users.

Accceptance Criteria

• [ ] When a batch proposal has an overall status of STATE_PASSED
  • [ ] Check all subproposals for their individual statuses
  • [ ] If all proposals have STATE_PASSED then overall status shoudl remain "Passed"
  • [ ] If any proposal has <> STATE_PASSED
  • [ ] Display "Passed with errors" on the overall status in top right of card
  • [ ] Next to the overall status (Proposal passed: conditions met for X of X proposals) add text indicating "but some proposals failed in execution, expand for details"
  • [ ] In the vote breakdown display additional red text indicating that proposal failed in execution along with the errorDetails given by Core
• [ ] In addition to this I think we should improve the colours on the overall status pill in the top right as I think currently they arent very intuitive:
  • [ ] Open proposals should be white
  • [ ] Passed & enacted proposals should be green
  • [ ] Declined or rejected proposals should be red
  • [ ] "Passed with errors" proposals as defined above should be yellow
  • [ ] If there are any other statuses found in implementation let me know
