Auto-reassign projects when juror declares conflict of interest

When a juror declares COI, the system now automatically:
- Finds an eligible replacement juror (not at capacity, no COI, not already assigned)
- Deletes the conflicted assignment and creates a new one
- Notifies the replacement juror and admins
- Load-balances by picking the juror with fewest current assignments

Also adds:
- "Reassign (COI)" action in assignment table dropdown with COI badge indicator
- Admin "Reassign to another juror" in COI review now triggers actual reassignment
- Per-juror notify button is now always visible (not just on hover)
- reassignCOI admin procedure for retroactive manual reassignment
