Unify futures odds with the simulation system
Make the futures-vs-Elo relationship an explicit, configurable rule and fix
futures odds failing to override stored Elo.

Root causes addressed:
- resolveSourceElos/resolveRatings used a hardcoded precedence (direct Elo ->
  projectedWins -> projectedTablePoints -> odds). The prior fix nulled sourceElo
  on futures entry but not projections, which still outranked odds.
- The override relied on a destructive null-on-save hack that also wiped
  manually entered Elo.
- Blended simulators buried their Elo/odds weight in module constants.
- Futures odds were not surfaced on the /admin/simulators inventory.

Changes:
- Add a configurable source policy: sourceEloPriority (ordered) and oddsWeight,
  parsed/clamped in getSimulatorInputPolicy. resolveSourceElos/resolveRatings now
  resolve each participant by the configured priority instead of a fixed order.
  Futures-centric simulators (ncaam, ncaaw, world_cup, ncaa_football,
  college_hockey) default to a futures-override priority.
- Drop the destructive nulling in batchSaveFuturesOddsForSimulator and
  batchSaveSourceOdds; override is now governed by policy, preserving stored Elo.
- Thread an optional SimulationContext (oddsWeight) through the Simulator
  interface so blended sims (UCL, World Cup, NCAA FB, MLB) read the blend weight
  from the season policy; defaults preserve prior calibration when no context is
  passed.
- Add a "Futures vs. Elo" strategy control and Odds Blend Weight input to the
  Simulator Setup input-policy card, persisted via save-input-policy.
- Surface futures on /admin/simulators: a source badge and a Futures Odds quick
  link; extend listSportsSeasonSimulatorSummaries with odds source info.
- Tests: configurable priority override (Elo/projections/rating), oddsWeight
  parsing/clamping, prefersFuturesOdds, manifest defaults, an NCAA Football
  context-blend behavioral test, and an updated non-destructive save test.

Add NCAA Football CFP simulator (12-team bracket) (#278)
Fixes #124

* Add NCAA Football CFP simulator (12-team bracket)

Implements a Monte Carlo simulator for the College Football Playoff using
the 2024-present 12-team format. Elo/FPI ratings are entered manually via
the existing admin Elo Ratings page; championship futures odds can
optionally be blended in (60% Elo / 40% odds).

- Add CFP_12 bracket template (First Round not scoring, QFs onward score)
- Add generateCFP12Bracket() with correct seeding: 5v12, 6v11, 7v10, 8v9
  in First Round; seeds 1–4 receive QF byes
- Add NCAAFootballSimulator: 50k Monte Carlo sims, seeds teams by blended
  Elo+odds strength, tracks champion/finalist/SF/QF placement tiers
- Register ncaa_football_bracket simulator type in registry and schema enum
- Add migration 0071: ALTER TYPE simulator_type ADD VALUE 'ncaa_football_bracket'
- Add tests: 30 tests covering bracket template structure and simulator
  probability distributions, seeding, edge cases, futures blending

* Fix lint errors in NCAA Football CFP simulator

Replace non-null assertions with optional chaining, change let to const,
use toSorted() instead of sort(), and add a bump() helper to avoid
repeated map lookups with non-null assertions in simulateBracket.

* Fix TS2345 in NCAA football simulator test

Add ?? 0 fallback so optional-chained probFirst is number, not number | undefined.
