Improved Copy-Paste and Cut Support, Dark/Light mode fixes

This release focuses on improving the copy-paste and cut functionality within the Tagger window and between the Tagger and Windows Explorer.

✨ New Features:

• Cut, Copy, and Paste in the Tagger: You can now use Ctrl+X, Ctrl+C, and Ctrl+V to cut, copy, and paste files and folders within the Tagger window.
• Overwrite Confirmation: When pasting files, you will now be prompted to confirm if you want to overwrite existing files.

🚀 Improvements:

• Windows Explorer Integration: Cut, copy, and paste operations between the Tagger window and Windows Explorer are now more reliable.
• Multi-Window Support: Pasting files now correctly targets the active Tagger window and the focused tree view, preventing accidental pastes in the wrong window.
• Dark mode: Implemented #8
• Bug Fixes: Fixed #6
