Pull Request Overview

This PR introduces a new BAM (Block Assembly Marketplace) Writer Service to track and calculate BAM delegation metrics according to JIP-28 specifications. It also extends the API with a new endpoint for BAM epoch metrics and enhances the validators endpoint with Jito pool eligibility information.

• Implements BAM writer service with automated epoch tracking and JIP-28 tier-based delegation calculations
• Adds new bam_epoch_metric API endpoint to expose BAM delegation data
• Extends validator data model with jito_pool_eligible and jito_pool_directed_stake_target fields
