relayscan service backfill-runner

[metachris]

Added relayscan service backfill-runner command that continuously runs the backfill + value-check operations:

# Test with just one relay (flashbots)
./relayscan service backfill-runner --relay fb

# Test with ultrasound relay and limited slots (last 50 slots)
./relayscan service backfill-runner --relay us --min-slot -50

# Combine flags for quick testing
./relayscan service backfill-runner --relay fb --min-slot -50 --skip-check-value

# Custom interval
./relayscan service backfill-runner --interval 10m

# Run once and exit (useful for testing)
./relayscan service backfill-runner --once

# Skip one of the steps
./relayscan service backfill-runner --skip-backfill
./relayscan service backfill-runner --skip-check-value

Pull request overview

This PR introduces a new backfill-runner service that continuously executes data-api-backfill and check-payload-value operations at configurable intervals. The implementation refactors existing command logic into reusable functions to support both CLI and service-based execution.

Key Changes:

• Introduced backfill-runner service with configurable execution intervals and relay filtering
• Extracted core backfill logic from CLI command into reusable RunBackfill function
• Extracted payload value checking logic into reusable RunCheckPayloadValue function with options struct

The BackfillOpts struct is defined but never used. The RunBackfill function takes individual parameters instead. Either remove this unused struct or refactor RunBackfill to accept BackfillOpts for consistency with CheckPayloadValueOpts in the other file.
