* Add MLB playoff simulator with AL/NL division standings, fixes#121
- New `mlb-simulator.ts`: 50k Monte Carlo sim drawing division winners
(weighted by p_div) and 3 WC teams per league, then simulating
WC best-of-3 → DS best-of-5 → LCS best-of-7 → World Series.
Elo parity factor 350; blends Vegas odds 30/70 when sourceOdds available.
- New `standings-sync/mlb.ts`: adapter for free statsapi.mlb.com API,
mapping AL/NL conferences, division ranks, streaks, home/away/L10 splits.
- New `mlb-divisions` display mode in RegularSeasonStandings: shows 1 division
winner per division section + Wild Card section with 3-spot playoff line,
headings read "AL/NL League" instead of "Conference".
- Refactored buildNhlSections/buildMlbSections into shared buildDivisionSections
(divisionSpots + wcSpots params); conferenceLabel now flows through group
objects rather than being derived from displayMode in the render.
- DB migration 0062 adds `mlb_bracket` to simulator_type enum.
- 37 new tests across simulator, adapter, and component.

* Fix flaky tennis simulator test: increase trials and lower threshold
500 trials with a ~3–5% expected win rate had enough variance to
occasionally land below the 0.03 threshold (~2% failure rate).
Bumping to 2000 trials reduces the std dev by 2x; lowering the
threshold to 0.02 keeps the assertion meaningful (still well above
random 0.78%) while eliminating the flakiness.

- Standings sync service with NHL (api-web.nhle.com) and NBA (ESPN) adapters,
externalId write-back for future syncs, and unmatched-team resolution UI
- `RegularSeasonStandings` component: flat (NBA) + division/wild-card (NHL) modes,
playoff line, TeamOwnerBadge, projected Brackt points (EV), mobile horizontal scroll
- Admin "Sync Standings" card + "Resolve Unmatched" UI on sports season page
- Admin manual standings edit hatch at /admin/sports-seasons/:id/regular-standings
- Show standings above bracket until matches exist; below once bracket is set
- `normalize-team-name` utility extracted to shared lib
