Overview

Add focus besluit mode to the meeting form

connected issues and PRs:

GN-5091

Setup

None

How to test/reproduce

Go to a meeting, you will have a switch on top, verify that when you activate the switch it correcly hides everything except the steps 1 3 and 5, also the publish and the copy buttons should be switched

Challenges/uncertainties

If we expect more custom modes to be added we could create a variable to show and hide each block and with the focus mode hide the sections we want, I didn't do it because I think there are no plans on the horizon for this, but I could be wrong.
Also awaiting for confirmation on the text of the tooltip

Checks PR readiness

• UI: works on smaller screen sizes
• UI: feedback for any loading/error states
• Check cancel/go-back flows
• Check database state correct when deleting/updating (especially regarding relationships)
• changelog
• npm lint
• no new deprecations
