User/chris/ev f1 framework (#93)
* feat: EV simulation framework with F1 Monte Carlo simulator

- Add EV snapshot tables (participant_ev_snapshots, team_ev_snapshots) and simulation_status column on sports seasons
- Add ev-snapshot model with upsert and history query functions
- Add simulator framework: types, bracket/F1/golf simulators, registry
- F1 simulator: vig-removed ICM weighted draw (pre-season) + race-by-race Monte Carlo from current standings (in-season); per-position column normalization to prevent floating-point EV drift
- Add admin simulate route and Run Simulation button on sports season page
- Rework futures-odds admin page to save odds then run simulation in one action
- Remove recalculate-probabilities route (superseded by simulate route)
- Remove EV trend chart panel and associated DB queries

* feat: map simulators to sports via simulatorType field

Adds a `simulator_type` enum column to the `sports` table so each sport
can be assigned a specific simulation algorithm rather than deriving it
from the sports season's scoring pattern.

- Add `simulatorTypeEnum` (f1_standings, indycar_standings,
  golf_qualifying_points, playoff_bracket) + `simulatorType` nullable
  column on `sports` table; migration 0037
- Rewrite simulator registry to key off `SimulatorType` instead of
  `ScoringPattern`; indycar_standings shares F1Simulator for now
- `findSportsSeasonById` now returns `SportsSeasonWithSport` so callers
  have typed access to `sport.simulatorType`
- Simulate and futures-odds actions read `sport.simulatorType`; guard
  fires before setting `simulationStatus: running`
- Admin sport edit page gains a Simulator Type dropdown
