.gitignore was ignoring these files, causing them to be missing
on fresh checkout (e.g. after git pull on server), which broke
the Docker build. Removed the ignore entries so the files are
tracked by git.
- Moved contents of main_dc/yalarba/easySite/easySite/ up to easySite/
- Updated docker-compose.yml build context path
- Deleted empty nested easySite/ directory
