Fix deployment: use rsync for reliable file copying

- Replace cp command with rsync for more reliable directory copying
- Ensures all files including styles folder are properly copied to root
- Add enhanced verification to check assets and main.css deployment
- Should resolve CSS loading issues on missingmaps.org

The rsync command is more robust than cp for CI environments and
will properly copy the entire _site directory structure.
