Update all simulators, services, and server files to use renamed schema tables:
- participants → seasonParticipants
- participantExpectedValues → seasonParticipantExpectedValues
- participantResults → seasonParticipantResults
- eventResults.participantId → eventResults.seasonParticipantId

Files updated:
- 20 sport simulators (NBA, NHL, NFL, MLB, etc.)
- probability-updater.ts
- standings-sync/index.ts
- sports-data-sync.server.ts
- server/socket.ts

Typecheck errors reduced from 365 to 0.

1bdd5c3372 Add snooker bracket simulator and Elo ratings admin UI, fixes #119 
- SnookerSimulator: Monte Carlo simulation of the 32-player World
  Championship bracket using per-frame Bernoulli win probabilities
  derived from Elo ratings (ELO_DIVISOR=700). Two paths: bracket-
  populated (respects completed matches) and pre-bracket (simulates
  qualifying, then seeds full draw).
- Admin route /sports-seasons/:id/elo-ratings: bulk-import and per-
  player Elo entry with fuzzy name matching; saves ratings and auto-
  runs the simulation in one action.
- schema: add snooker_bracket simulator type, source_elo column on
  participant_expected_values, unique index on (participant_id,
  sports_season_id).
- Fix batchSaveSourceElos to use INSERT ... ON CONFLICT DO UPDATE
  instead of N+1 SELECT+UPDATE loop.
- Fix existingElos returned as plain Record (Map doesn't survive JSON
  serialization through useLoaderData).
- Fix "How It Works" formula to show correct divisor (700, not 400).
