feat: add logging setup and standalone mode detection to LoRA Manager

- Initialize logging configuration via `setup_logging()` when not in standalone mode
- Detect standalone mode using environment variables `LORA_MANAGER_STANDALONE` and `HF_HUB_DISABLE_TELEMETRY`
- Remove redundant `STANDALONE_MODE` variable that previously checked `sys.modules`
