feat: add multi-site configuration script

- Create configure-sites.sh to generate per-site Grav configs
- Generates system.yaml, site.yaml, and default home page
- Configures all 22 sites with appropriate titles
- Script executed in container to configure all environments

Each site now has:
- config/system.yaml: Grav system settings (quark theme, caching)
- config/site.yaml: Site metadata (title, author, description)
- pages/01.home/default.md: Placeholder home page
