Fix anonymous access 500 error and add environment variable control

- Fixed dashboard.html template error accessing current_user.username for anonymous users
- Added ALLOW_ANONYMOUS_ACCESS environment variable with default true
- Enhanced index route logic to properly check config before allowing anonymous access
- Added proper environment variable to docker-compose.yml
- Anonymous access now works without 500 server errors

Fixes issue #2 completely - anonymous access is now functional
