Address code-review findings: ping guard, dual filter, inline helper

- Restore winnerScoreChanged guard on winnerDiscordUserId so advancing-only
  winners are shown in the embed but not Discord-pinged
- Add display-name filter at the end of the scoredMatches chain so
  scoredMatches always reflects exactly what appears in the embed, eliminating
  the dual-gate split between scoring-calculator.ts and discord.ts
- Remove isMatchNotable export and inline x.winnerScoreChanged || x.showLoser
  at its sole call site; move the reasoning into the existing comment block
