US-7: Indication of status for applications based on AI models

[andreaslhjulstad]

As an application approver, I want a status indication for applications with obvious deficiencies to be clearly marked,
so that I can easily identify applications that need to be returned or require further attention.

Linked issues:

• Status indication on overview page #24
• On-hover pop-up for status indicator #25

Acceptance criteria:

• The overview of applications should have a column for status that shows if it has deficiencies or is ready to be approved. There should be three different statuses:
  • “Fullført” - Green check
  • "Noen mangler" - Orange warning sign
  • "Betydelige mangler" - Red X
• The status indication aggregates results from the models and displays it as a simple icon
• When the user hovers over the indication, they are presented with a more detailed view of what is missing.
