feat: migrate config from INI to TOML format

- Replace configparser with toml crate
- Refactor Monitor struct to hold MonitorType directly
- Fix broken Monitor::Display implementation
- Update wallpaper handlers to use new Monitor API
- Change default config path to .toml
- Suppress dead_code warnings on auto-generated D-Bus code
