[x] remove ordering asc desc as its not really needed
[x] Add correct cursor pointer css for dragging on cards
[x] solve problem with null/0 for position. Moving something to the end is currently not working
[x] Better css styling for insertion template
[x] Drag & Drop only for admins. Optional: Setting in admin area to allow for all.
[x] Fix ordering logic: When card is move from beginning to end, there are ordering gaps. Idea: Use window function to restore proper ordering: 1) Set the moved card to new position, e.g. from update position 1=>7, then update by sorting by position and last updated and use window function to get a proper ordering again.
