feat(src/hardware): add logging for detected NVIDIA GPU and refactor command calls

Add `info!` logging when a NVIDIA GPU is discovered via `lspci`, enhancing debug visibility. Refactor the `lspci` and `xrandr` command constructions into multi‑line style for consistency and prepare a regex for future AMD GPU name detection.

- New Features: Log GPU detection with `info!` macro.
- Enhancements: Refactor command calls for readability; introduce regex preparation for AMD detection.
- Bug Fixes: None.
