feat(server): migrate all logging to pino

- Add pino with pino-pretty for structured logging
- Create root logger in index.ts with child loggers per module
- Support log level via PASEO_LOG env var and config.json
- Support log format (pretty/json) via PASEO_LOG_FORMAT and config.json
- Replace all console.* in runtime code with appropriate log levels
- Scripts use process.stdout/stderr for output
- Error logging uses correct pattern: logger.error({ err }, msg)
