Fix: Change 'amount' to 'price' to match database schema - Database uses 'price' column, not 'amount' - Update all queries in DailySummaryService, HourlySummaryService - Update RetribusiWriteService (SELECT, INSERT, UPDATE) - Update Validator to use 'price' field - Update check_database.php and TROUBLESHOOTING.md
