202-Bug fix bracket progress showing wrong round numbers

[RemainingDelta]

Changes

• Fixed bracket progress embed displaying round numbers off by one — when participant count is ≤ half the bracket size, Matcherino gives every team a first-round BYE, causing resolved_round to start at 2+ after BYE filtering. Round numbers are now normalized so the first real round always displays as Round 1.

Round (before)	Round (after)	Match numbers	Actual (Matcherino site)
Round 2	Round 1	1–15	Round 1
Round 3	Round 2	16–47	Round 2
Round 4	Round 3	48–63	Round 3
Round 5	Round 4	64–71	Round 4
Round 6	Round 5	72–75	Round 5
Round 7	Round 6	76–77	Round 6
Round 8	Round 7	78–79	Round 7

*Verified against tournament 191034 (79 teams, 256-slot bracket).
