Session 51: Complete Team Hub (2234 tests)

Research-depth team view: /team/[abbr] with roster, archetypes, stats, props.

- Team API: mlbStatsAdapter.getTeams/resolveTeam/getTeamRoster (statsapi, abbr→id
  + active roster, cached). teamService.getTeamHub assembles roster → per-player
  season stats (bounded concurrency) + archetype (snapshot grade or classify) +
  tonight's graded props from grades:{sport}; whole hub cached 15min. MLB real;
  NBA/WNBA graceful snapshot roster. GET /api/team/:abbr (404 unknown) + proxy.
- Team Hub page: server page.tsx (generateMetadata) + TeamHub client — header,
  sort (archetype/graded/A-Z), archetype filter chips, roster rows (archetype +
  player link + position + stats + graded props + parlay "+"), "No active props"
  greyed state, loading/error.
- Game cards: team abbreviations are now TeamLinks → /team/:abbr?sport= (green
  hover, stops propagation). Team Hub has "← Back to Slate".

Backend 2215 -> 2234 tests (+19), 190 suites. Web build clean (exit 0).
