refactor: normalize Jinja2 spacing in volume paths and add async support in backup task

- Standardized spacing in {{ docker_compose.directories.volumes }} across multiple roles
- Added async and poll support to sys-bkp-docker-2-loc database seeding and file permission tasks
- Moved Installation.md for web-app-matrix into docs/ for better structure
