Show pending bias deputy reservations in participant status

Stress Cyclone reserved Deputy 11 for a pending bias replacement. Candidate exclusion correctly prevented that person’s other list roles from being selected elsewhere, but every participant card still labeled Deputy 11 as `Ledig vara`. Display canonical/declaration-backed reservation intent on the reserved person’s participant rows, including multi-list roles, without granting voting rights before approval. Clear/update the status on withdrawal, rejection, deputy change, and completed decision.
