assignColony() never checked the queen's own status, so a queen marked
LOST/DECEASED/REPLACED/SOLD - exactly the statuses the queen-loss fix
now treats as "not really available" and releases her from her old
colony for - could still be assigned to a brand new colony, which
makes no domain sense (you can't put a dead queen in a hive).
Rejects with ConflictException up front, before even looking up the
destination colony; correcting a mistaken status update first is the
intended fix path.
