FE: Add Status widget in the sidebar of Task work item

Summary

Add ability to show current status or change status in the Task work item sidebar.

1. First spike Spike: Work item status widget - Iteration 1 (#477863 - closed)
2. POC which contains parts of the FE widget Draft: POC Static default status for work items (!178180 - closed)

• only task will have ability to show and change the status - doesn't matter because of widget availability ✅
• the default status of an open work item will be Todo - doesn't matter happens on backend ✅
• the default status of an open work item will be Done - doesn't matter happens on backend ✅
• on edit, a listbox with search ability would appear in the sidebar
• once user select the status, call the mutation to change the status if
  • user clicks outside the listbox
  • user clicks on the Apply button

Acceptance criteria

• Task will have a Status widget with default status based on the work item state (open/close) (status is always fetched from backend and only displayed if status widget is available, if not display none) in the sidebar of the detail page
• It will have the ability to show the status received from the GraphQL query
• It will have the ability to change the status
• Once the status is changed, updated the new status should appear in the sidebar
• On error, show message as per other sidebar widgets
