[Enhancement] KanBan: Save Order Of Issues on Boards

[6543]

Add a filed ProjectBoardOrder or use Priority from/to Issue struct.
0 = default
highest number is on the top of the list ...

thoughts how to impement the backend:

issue with prio 4 -> 2:
new prio is lower so "Update prio=prio+1 where issue.project_id= .... and prio >= 2 and prio < 4"
issue with prio 3 -> 7:
else "Update prio=prio-1 where issue.project_id= .... and prio > 3 and prio <= 7"
x.ID(issue.id).UpdateCol(prio=newPrio)

Pseudo code don't take it to serious

Unfortunately PR #12506 has been closed by @patcito that "cannot commit to redo the backend" (needed to fulfill reviewer requests). Is there any plan for a sustainable order of issues in the kanban ?
