Notes from task breakdown:

• create a web endpoint that receives mismatches and updates them in the database (T292050)
  • payload is expected to be an array of full mismatch data, including the updated review_status
  • can't re-use the existing single-mismatch MismatchPutRequest
  • create new batch validation rules (can't re-use the single-mismatch rules)
  • respond with a redirect back to the results page (which will pick the new results from the db and display them on the page)
  • feature test the new route

• send mismatches from the internal Resultspage data model to that endpoint on submit (T292054, depends on T289557)
  • create one form for each result (i.e. item), with the mismatches table and a submit button
  • submitting the form will trigger a handler to send the data
  • the buttons will be disabled until the new endpoint task is done
  • write a unit test for the Results page that mocks $inertia (see Home.vue) and makes sure that the put method is called with the correct URL and payload
  • payload is expected to be an array of full mismatch data, including the updated review_status

• tie together changed frontend data model with the endpoint (T292058, depends on T292050 and T292054)
  • enable the submit buttons
  • test e2e behaviour with browser tests: user can submitting a selected value and the new state appears on the results page

• handle errors and display a Wikit message in the same way as done on the Home page (see T289344) (T292055)
  • triggers on response statuses >=500 (handled in \App\Exception\Handler.php already)
  • modify the existing redirect(route('home') in Handler.php to something more generic like back()
  • Figma design
  • maybe move the shared error message box including styles into its own vue component (and replace in Home.vue)
  • test e2e behaviour with browser tests
