Introduce `serverLogger` utility based on pino for consistent, structured logging across all server and API modules. Replace direct console logging with `serverLogger` and add request-scoped logging helpers. Update environment variable handling, documentation, and deployment guides to reflect new logging configuration (`LOG_FORMAT`, `LOG_LEVEL`, `COMPUTE_LOG_LEVEL`). Enforce no-console in server code via ESLint and add pino/pino-pretty dependencies.
This change standardizes log output, improves observability, and prepares the codebase for ingestion by log platforms.
