Subject: [PATCH] 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).

+/**
+ * Snooker World Championship Simulator
+ *
+ * Monte Carlo simulation of the World Snooker Championship (Crucible, Sheffield).
+ * The tournament is a 32-player single-elimination bracket with 5 rounds, using
+ * best-of frame formats that increase in length each round.
+ *
+ * Algorithm:
+ *   1. Load the bracket scoring event and all playoff matches from DB.
+ *   2. Load Elo ratings from participantExpectedValues.sourceElo.
+ *   3. Compute per-match win probability using the Bernoulli frame model:
+ *        p_frame = 1 / (1 + e^(-(Elo1 - Elo2) / ELO_DIVISOR))
+ *        P(win match) = sum_{w2=0}^{F-1} C(F-1+w2, w2) * p^F * (1-p)^w2
+ *      where F = frames to win, which varies by round.
+ *   4. Two simulation paths:
+ *      a. Bracket populated: simulate from actual draw, respecting completed matches.
+ *      b. No bracket: simulate qualifying (ranks 17-48 play one round best-of-19),
+ *         randomly pair 16 winners vs top 16 seeds, then simulate 5-round bracket.
+ *   5. Track integer placement counts per tier across 50,000 simulations.
+ *   6. Convert to probability distributions using exact denominators (column sums = 1.0).
+ *
+ * Round format (Crucible main draw):
+ *   First Round  (R32): best-of-19, first to 10
+ *   Second Round (R16): best-of-25, first to 13
+ *   Quarter-Finals (QF): best-of-25, first to 13
+ *   Semi-Finals   (SF): best-of-33, first to 17
+ *   Final:              best-of-35, first to 18
+ *
+ * Placement bucketing (8-slot probability model):
+ *   probFirst          → Champion
+ *   probSecond         → Finalist
+ *   probThird/Fourth   → SF losers (2/sim)
+ *   probFifth–Eighth   → QF losers (4/sim)
+ *   R16 losers         → all 0
+ *   R32 losers         → all 0
+ *
+ * World rankings (for pre-bracket path): hardcoded below. Update annually.
