Price Parlay

Combine multiple legs into a parlay and return per-bookmaker combined odds. iteration_022 #209: in a product called ParlayAPI, callers had to client-side multiply decimal odds across N /odds calls themselves; this endpoint does that work server-side.

Cost: 2 credits per leg (min 4).

Request body:

{
  "legs": [
    {"sport_key":"basketball_nba","event_id":"<id>",
     "market":"h2h","outcome":"Cleveland Cavaliers"},
    {"sport_key":"soccer_epl","event_id":"<id>",
     "market":"h2h","outcome":"Tottenham Hotspur"},
    {"sport_key":"baseball_mlb","event_id":"<id>",
     "market":"totals","outcome":"Over","point":9.0}
  ],
  "bookmakers": ["fanduel","draftkings","betmgm"]
}

Returns one entry per bookmaker that prices ALL legs, sorted by combined decimal odds DESCending (best to worst). Books missing even one leg appear in missing_books with which legs they couldn't price. SGP flag set when 2+ legs share the same event_id; raw multiplication is the LOWER bound for SGP (real books apply a correlation discount we don't replicate).
