Session 54: Audit cleanup — name edges + polish (2255 tests)

P1 name edge cases (BOTH playerName.js copies, kept identical):
- normalizeName strips hyphens (display+key): "Jung-hoo Lee" === "Jung Hoo Lee".
- nameKey strips single-letter MIDDLE tokens: "Josh H Smith" === "Josh Smith"
  (keeps first+last; real middle names + collapsed initials untouched).
- richie -> richard added to NICKNAMES.

P2 polish:
- Team Hub names normalized at the source (teamService.getTeamHub) so
  "J.C. Escarra" renders as "JC Escarra" like the dashboard.
- snapshotService dedup keeps the highest-confidence GRADE but the richest
  DISPLAY (accented "José" over "Jose") so prop rows match the pitcher line.
- correlationWarning names the game: "2 legs from the same game (NYY @ BOS)".

Backend 2246 -> 2255 tests (+9), 194 suites. Web build clean (exit 0).
