feat: indexer added

[okekefrancis112]

🎯 Implementation Description
TeachLink Indexer is a production-ready NestJS application that continuously monitors the Stellar blockchain for TeachLink Soroban smart contract events via the Horizon API. It indexes all 18+ event types (bridge operations, rewards, escrows, content tokenization, and credit scoring) into a PostgreSQL database with proper relationships and indexes. The indexer features automatic state persistence for resume capability, historical backfill support, health monitoring with auto-restart, comprehensive error handling, and full Docker containerization. Built with TypeScript for type safety, it includes extensive unit and integration tests, supports both development and production environments, and provides a scalable foundation for building analytics dashboards and applications that require efficient access to contract data.

Closes: #54
