Allow directing new products to other projects #2590
Description
What
- Allow directing new products to other projects
- Allow to pick the project
- Make it possible to send the API route on the fly for the product addition screen
- Redirect to a prompt to install the other apps (for the time being, and just for OBF in the case of iOS)
Why
- People keep adding non-food items to Open Food Facts (and even thank us for cosmetic support which isn't there)
