Add 2-in-1-tools plugin

[luna-araujo]

Summary

• Add the 2-in-1-tools plugin for display rotation controls on Niri and Hyprland
• Include bar and Control Center widgets, settings UI, tablet-mode automation, and Hyprland touchscreen transform sync
• Add the required 960x540 preview image

Validation

• Tested locally in Noctalia Shell on Hyprland
• Verified tablet-mode detection via Hyprland socket/state-file watcher and fallback polling
• Verified auto-rotate starts/stops and restores display rotation to normal when leaving tablet mode
• Ran registry generation locally and confirmed the plugin is discovered; registry.json is intentionally not included
