We already have the possibility to duplicate a Media.
Let's also allow to duplicate a POI.
- Frontend - example: https://beta.atlas.landscapefor.eu/poi-duplicate.php?poi_ID=18972
- copy POI basic fields
- deep-copy the thumbnail (so if you delete the new POI, you do not delete the old POI's thumbnail)
- inherit all language-based fields
- inherit related Medias
- add quick action from POI edit page (footer)
- inherit Archives
- inherit related POIs
- inherit related Tags
- inherit group permissions
