fix(plugins): Fix uninstall permission errors and Python path issues

- Fix Python path: Replace /usr/local/CyberCP/bin/python with python3 (path doesn't exist)
- Fix removeFiles(): Add permission fixing before deletion to handle .DS_Store, __pycache__, etc.
- Improve 'already installed' check: Only consider plugin installed if meta.xml exists
- Auto-cleanup incomplete plugin directories during install
- Add fallback to rm -rf if shutil.rmtree fails

Fixes:
- [Errno 2] No such file or directory: '/usr/local/CyberCP/bin/python'
- [Errno 13] Permission denied: '.DS_Store', '__pycache__', 'README.md'
- Plugin already installed: discordAuth (when directory exists but incomplete)
