Python triple-quoted string interprets \n as literal newlines,
producing invalid JS string literals and a SyntaxError that
killed the entire script block.

Each dataset page now has an "Explain this dataset" button that calls the
NVIDIA NIM chat completions API (meta/llama-3.3-70b-instruct) directly from
the browser with headers + first 10 rows as context. API key is entered via
a settings modal and stored in localStorage only — never sent to the server.

- Rewrite webview serve.py to query PostgreSQL analytics tables via psycopg2
instead of reading CSV files from PVC; PVC mount removed from Deployment
- Remove isPgnMode guard from all 4 original jobs so results always write to DB
regardless of whether input comes from game_records or a Lichess PGN dump
- Add JDBC write-back to all 7 new analytics jobs (game_length_distribution,
game_length_by_result, color_advantage, elo_distribution, time_control_stats,
hourly_activity, weekly_activity, rating_mismatch, termination_stats)
- Add analytics_component_sizes JDBC write to PlayerGraphJob
- Add NOWCHESS_PGN_PATH staging patches for the 7 new CronJobs

Adds CronJobs and headless driver Services for GameLengthJob, ColorAdvantageJob,
EloDistributionJob, TimeControlJob, DailyActivityJob, RatingMismatchJob, and
TerminationStatsJob. All suspended by default; scheduled Saturday mornings.
Adds spark-analytics-webview: a stdlib Python HTTP server (ConfigMap + Deployment
+ Service) that reads CSV output from the spark-analytics-output PVC and renders
13 datasets as browsable HTML tables. Disabled (replicas=0) in base.
Staging overlay enables the webview (replicas=1), exposes it via Ingress at
spark-results-st.nowchess.janis-eccarius.de, and sets NOWCHESS_PGN_PATH on all
CronJobs to the Lichess Jan-2013 rated standard PGN dump for demo runs without
a NowChess database.
