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).

+- `normalizeName` now also **strips hyphens** to spaces ("Jung-hoo" → "Jung hoo")
+  in display+key; `nameKey` **strips single-letter MIDDLE tokens** ("Josh H Smith"
+  → "josh smith") — keeps first (may be a collapsed initial like "jc") + last, so
+  real middle names ("Juan Carlos Smith") and first initials are NOT dropped.
+  `richie: 'richard'` added to NICKNAMES. Both copies kept identical.
+- **Accent-keep dedup** (`snapshotService`): the variant-grade collapse keeps the
+  highest-CONFIDENCE grade but the richest DISPLAY (prefers accented "José" over
+  "Jose", then longer). That's why prop rows now match the accented pitcher line.
+  `hasAccent` uses a charCode>127 check (NOT a regex with literal control bytes).
+- **Team Hub names** are normalized in `teamService.getTeamHub` (the source), not
+  the page — every `/api/team/:abbr` consumer gets `normalizeName().display`.
