fix: don't mark next round as current before advancement is declared

The applicant timeline sidebar was treating any previous round with
status ROUND_CLOSED as "advanced past", which caused the Grand Finale
to show "You are here" as soon as the semi-final round closed — before
admins declared which teams actually advanced.

Require explicit PASSED/COMPLETED project state on every prior round
before marking the next one as current. A closed-but-unresolved round
now correctly keeps the applicant anchored to it.
