The manager's Start button flips el3ab_tournaments.status to in_progress
directly. For a tournament this engine owns, nothing else was ever going to pair
round 1 — so the tournament sat registered, started, and permanently unplayable,
with current_round 0 and no round row.

tournamentTick now opens the round when it finds that state, which also repairs
any tournament already stuck in it. Covered by e2e section 21.
