"""Archive round data on reopen instead of overwriting it.

Reopening a test for rework used to reset the live procedure/result fields
in place, losing the prior round's data (and clobbering the Phase Timeline,
which read those same mutable columns). This adds an append-only
``test_round_history`` table that snapshots a round's fields right before
they get reset, plus per-team round counters on ``tests`` so each round is
numbered.
