Session 46: Grade card intel + name normalization + pitchers (2122 tests)

Three focused P1 fixes on the Session-45 snapshot model.

- Grade card intel ROOT CAUSE: gameLogService is NBA/WNBA-only (offline Python),
  so MLB props never got l5_avg/l20_avg and buildIntelFields returned {}. Wired
  MLB game logs into featureCache.gameLogFeatures via mlbStatsAdapter.getPlayerStats
  (pure mlbGameLogFeatures + MLB stat_type->field map). buildIntelFields gained
  playerStats/projection fallbacks for partial intel.
- Player name normalization: src/utils/playerName.js (+ web/src/lib copy):
  normalizeName -> {display,key}. Strips periods, de-dots suffix, accent-folds
  the key. Applied in snapshotService grouping, slateAdapter grade index +
  player-strip merge (variants collapse, longest name shown), and
  playerIntelService. "A.J. Ewing"/"AJ Ewing" + "Jazz Chisholm"/"Jr." now merge.
- MLB starting pitchers: new GET /api/schedule/:sport/pitchers (probablePitchers
  service wrapping mlbStatsAdapter.getScheduleWithPitchers + best-effort ERA).
  Slate fetches it, builds a team->pitcher map (full name + mascot match),
  attaches pitchers to MLB GameCardData. + Next proxy.

Backend 2100 -> 2122 tests (+22), 176 suites. Web build clean (exit 0).
