Edit element rotation, using specific angles
Depends on #690 (closed)
Add a new component in the details panel that allow rotating images, only using specific angles:
- 0 (reset)
- 90
- 180
- 270
Ideally every change should trigger a display update (and API call), but this could totally be a followup. The first version should add a "Save" button to that form, making a single update API call & display update
