fix(ncs-122): authenticate WebSocket connections via first-message auth

Replace header-based auth (not possible with browser WebSocket API) with a
first-message auth protocol: client sends {"type":"auth","token":"<JWT>"}
as the first text frame; server validates and proceeds or closes the connection.

Both GameWebSocketResource and UserWebSocketResource now hold incoming
connections in a pendingAuth set until the auth frame arrives, preventing
any game or event messages from being processed before identity is established.

Also removes the broken Bearer-prefix handling that caused header-based auth
to silently fail even for non-browser clients.

-/** Per-move accuracy & blunder analysis mined from Lichess `[%eval ...]` move annotations.
-  *
-  * Unlike the flat single-`groupBy` summaries (opening rates, colour advantage), this job reconstructs the *quality of
-  * every move* from the engine evaluations Lichess embeds in the movetext (`{ [%eval 0.24] }`, mate scores `[%eval
-  * #-3]`) and turns them into the same accuracy signals lichess.com surfaces: average centipawn loss (ACPL), and counts
-  * of inaccuracies / mistakes / blunders.
-  *
-  * Pipeline (all Spark SQL string/array functions + window funcs — no UDFs, Catalyst-friendly):
-  *   1. Keep only games carrying `[%eval` comments.
-  *   2. `regexp_extract_all` pulls every eval in ply order; mate scores collapse to ±10 pawns, normal evals are clamped
-  *      to ±10 so a single huge swing cannot dominate the mean. All evals are White-POV pawns.
-  *   3. `posexplode` → one row per ply; a per-game window `lag` gives the eval *before* the move.
-  *   4. Centipawn loss for the side that moved = how much the eval moved against them (white wants it up, black down),
-  *      floored at 0 and scaled to centipawns.
-  *   5. Roll up to (game, side): ACPL + inaccuracy(≥50cp) / mistake(≥100cp) / blunder(≥200cp) counts, tagged with that
-  *      side's Elo and whether they won.
-  *
-  * Outputs (Parquet + CSV + JDBC):
-  *   - `accuracy_by_rating` — ACPL, avg blunders/mistakes/inaccuracies per game and win-rate, per Elo band. Shows how
-  *     move quality scales with rating.
-  *   - `blunder_outcome` — win-rate bucketed by number of blunders in the game. Quantifies "one blunder costs you the
-  *     game".
-  *
-  * Requires the eval-annotated Lichess dump (`NOWCHESS_PGN_PATH` → an evals dump); JDBC games carry no per-move evals.

-  * per-move thinking time and remaining-time from those stamps to answer questions the existing time-control summary
-  * cannot: how long do players actually think, how often do they fall into time scrambles (<10 s left), how often do
-  * they flag (lose on time), and does burning the clock correlate with winning?
-  *

-  *   3. A per-(game,side) window `lag` gives the same side's previous clock; the difference is that move's thinking time.
-  *      Remaining clock <10 s marks a time-scramble move.
-  *   4. Roll up to (game, side): avg move time, scramble fraction, min clock, Elo, win flag, and whether the side lost on
-  *      time (`Termination "Time forfeit"`).

-  * Outputs (Parquet + CSV + JDBC):

-/** Smurf / sandbagging anomaly detection via population z-scores.
-  *
-  * Smurfs (strong players on fresh accounts) and sandbaggers leave a statistical signature: a win-rate, an upset-rate
-  * (beating higher-rated opponents) and a self-Elo climb that sit far above the population norm. This job builds those
-  * three features per player, standardises each against the whole player base, and flags the players whose combined
-  * deviation is extreme.
-  *
-  * Features per player (from each game's own/opponent Elo):
-  *   - win_rate — fraction of decisive results won
-  *   - upset_rate — wins vs higher-rated opponents / games vs higher-rated opponents
-  *   - elo_climb — max self-Elo − min self-Elo across their games (rapid rating gain)
-  *
-  * Standardisation uses a single unbounded window (`Window.partitionBy()`), i.e. mean/stddev over every qualifying
-  * player, so z = (x − μ) / σ. The composite anomaly score sums the three z-scores. No UDFs — pure SQL aggregates +
-  * window functions, so Catalyst plans the whole job.
-  *
-  * Outputs (Parquet + CSV + JDBC):
-  *   - `anomaly_scores` — every qualifying player with features, z-scores and composite, ranked most-anomalous first.
-  *   - `flagged_smurfs` — the suspicious subset (high composite, or the classic high-winrate / few-games / steep-climb
-  *     profile).
-  *
-  * Meaningful only when Elo is present (Lichess dump); requires `minGames` (arg 1, default 15) to avoid small-sample
-  * noise.
