fix(obs): align stdout log level with configured logger_level

- Replace fixed `flexi_logger::Duplicate::Info` with dynamic level from config
- Convert logger_level string to corresponding LevelFilter enum
- Ensure terminal output respects the same log level as file logs
- Fix documentation to reflect the dynamic level behavior
