Fix the Best Bets Failure; remove duplicates on front page

[gmalbert]

This pull request updates the nightly pipeline outputs and underlying data files to reflect the latest run and data refresh. The main changes include new match data and odds, updates to value bets, and a significant pipeline error related to missing Parquet support. Additionally, the workflow configuration was slightly adjusted.

Data and Pipeline Updates:

• Updated all cache files (odds_history.json, matchup_edge_history.json, playoff_probabilities.json, player_props.json, points_table.json, schedule.json, shot_locations.json, value_bets.json) to reflect the latest data run, including new matches, odds, and value bet recommendations.

• Added new scheduled matches, including "Nepal vs Netherlands" with associated odds and a new value bet recommendation for "Nepal ML" (+150 odds, 2.4% Kelly stake). [1] [2] [3]

Pipeline and Error Reporting:

• Updated the pipeline manifest (run_manifest.json) to reflect the latest run, showing a reduced number of processed records and a new error: missing Parquet engine (pyarrow or fastparquet), which caused Cricsheet data to be skipped.

Workflow Configuration:

• Removed the continue-on-error: true directive from the "Export best bets" step in the nightly GitHub Actions workflow, so failures in this step will now cause the workflow to fail.

Best Bets Export:

• data_files/best_bets_today.json was regenerated, clearing the previous export failure note.
