test(format): pin the sub-minute truncation (E9 R2)

Round 2 mutation-checked round 1's own fix and found the one line it left uncovered: every table row was an integer, so `Math.floor(sec)` in the new seconds tier could be deleted or swapped for round/ceil with the suite still green — exactly the "later cleanup removes it as redundant" failure the fix's comment claims to prevent. Two fractional rows kill all three mutants.
