Description

What is added

1. Added additional statuses (todo, in progress, in review, done, not implemented). Note that this also means adding additional colours to the status bar icon in the measures in the requirements overview. Since the status bar only has a limited set of colours, this is now suboptimal visually. The current colours are aligned with Ruben.
2. Possibility to add URI's to files. The input field is not checked, so any user input will be stored in the system card under the corresponding measure in the field links.
3. Possibility to upload files. NOTE: it was decided to REMOVE the file list when adding files, before saved is pressed.
4. Possibility to download an uploaded file from the object storage.
5. Possibility to remove the uploaded files.
6. Added tests for the new ObjectStorageService
7. Added tests for the new GET and DELETE endpoints for the files

What is not added

1. Automatically render an icon according to the file extension. For example a PDF logo for a PDF file.
2. A progress bar for uploading files.

What still needs to be done

1. (very OPTIONAL) remove the coupling of the ObjectStorageService with Minio, maybe by using protocols or something.
2. Code review
3. Code review + merge of the PR in the infra repo: Add env vars for minio service ai-validation-infra#85
4. Check if everything works on staging
5. Merge the PR

Estimation of leftover points: 1 or 2.

If things don't work properly

-> Berry probably knows most about the Minio side of things
-> Robbert U knows probably most about the way the UI of the form is implemented

How to tests things locally

Use a local instance of Minio with the settings which are specified in the core settings in AMT.

Resolves #361
