* Refactor telemetry initialization and environment functions ordering

- Reorder functions in envs.rs by type size (8-bit to 64-bit, signed before unsigned) and add missing variants like get_env_opt_u16.
- Optimize init_telemetry to support three modes: stdout logging (default error level with span tracing), file rolling logs (size-based with retention), and HTTP-based observability with sub-endpoints (trace, metric, log) falling back to unified endpoint.
- Fix stdout logging issue by retaining WorkerGuard in OtelGuard to prevent premature release of async writer threads.
- Enhance observability mode with HTTP protocol, compression, and proper resource management.
- Update OtelGuard to include tracing_guard for stdout and flexi_logger_handles for file logging.
- Improve error handling and configuration extraction in OtelConfig.
