Add commissioner replace pick and draft rollback features (#18)

Commissioners can now right-click any picked cell in the draft grid to
replace the drafted participant (available during and after draft) or
roll back the draft to that pick number (available during draft only).

Replace pick enforces sport eligibility with the replaced slot treated
as free, updates the pick in-place, and broadcasts a pick-replaced
socket event so all clients update in real time. Rollback deletes all
picks from the selected pick onward, resets the season pick number,
clears all timers, and creates a fresh timer for the team now on the
clock.
