Fix deployment workflow: improve file copying and add debugging

- Replace find command with more reliable bash loop for file cleanup
- Add comprehensive debugging output to track deployment process
- Improve error handling and verification for _site content copying
- Handle hidden files properly during deployment
- Add verification steps to ensure CSS and assets are properly deployed

This should resolve the main.css loading issue on missingmaps.org by ensuring
files are properly extracted from _site to root of master branch.
