Now all counts share one connection. BrokenPipeError on probe disconnect silenced.

Handle URLs without explicit port, show DB_HOST:PORT/DB_NAME in error messages
and startup log to simplify connection debugging.

- 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.
