Add regular season standings for NBA/NHL (fixes #89) (#192)
Adds live standings sync and display for bracket-based sports (NBA/NHL),
so league members can see W/L tables and which teams their opponents drafted
during the regular season — not just after the playoff bracket is set.

- New `regular_season_standings` table with upsert-on-conflict sync
- 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

Add NBA playoff bracket Monte Carlo simulator (#154)
Adds a new `nba_bracket` simulator that projects both regular season
seedings and the full NBA playoff bracket, unlike other simulators that
operate on a pre-set bracket stored in the DB.

Algorithm:
- Per iteration: each team draws a conference seed (1–10) weighted by
  BBRef seed probabilities, then seeds 7–10 play the Play-In tournament
  (single elimination), then the resulting 8-team bracket is simulated
  as best-of-7 series using Elo playoff ratings
- Elo source: playoff rating (last 110 games, no regression to mean,
  postseason games weighted 3×) — appropriate for playoff matchup quality
- Seed probs source: Basketball-Reference (March 16, 2026), scaled from
  conditional to unconditional by multiplying by each team's Playoffs%

Placement tiers map to SimulationProbabilities:
  probFirst/Second → NBA champion / Finals loser
  probThird/Fourth → Conference Finals losers (2 per sim)
  probFifth–Eighth → Conference Semis losers (4 per sim)

Files:
- app/services/simulations/nba-simulator.ts (new)
- drizzle/0046_add_nba_bracket_simulator_type.sql (new)
- database/schema.ts: adds `nba_bracket` to simulatorTypeEnum
- app/services/simulations/registry.ts: registers NBASimulator
