Payer reports: do not report others as frequently

[mkysel]

Add distinct payer report generation periods to configure self at 6h and others at 12h and update workers to use these durations

This change introduces separate configuration for payer report generation periods for self and others and updates the worker pipeline to consume these values. It adds two time.Duration fields to config.PayerReportOptions, threads them through server initialization, validates them in the worker config builder, and updates the generator worker to apply the correct interval based on report origin.

• Update configuration to add GenerateReportSelfPeriod (default 6h) and GenerateReportOthersPeriod (default 12h) in options.go
• Modify workers.GeneratorWorker to hold generateSelfPeriod and generateOthersPeriod and select between them in workers.GeneratorWorker.isOlderThanReportInterval in generator.go
• Extend workers.WorkerConfigBuilder with WithGenerationSelfPeriod and WithGenerationOthersPeriod, validate periods > 0 in Build, and pass them in RunWorkers in runner.go
• Wire new options through server construction in server.go
• Adjust tests to use the new constructor signature and set short periods in test options in integration_test.go and server.go

📍Where to Start

Start with the worker configuration flow in workers.RunWorkers and workers.WorkerConfigBuilder.Build to see how periods are validated and injected, then review workers.GeneratorWorker.isOlderThanReportInterval for the selection logic in runner.go and generator.go.
