Restore production deploy infrastructure with static.europython.eu

Replace development server references in deploy configuration with the
production static.europython.eu host and restore the releases/symlink
deployment pattern.

- Makefile: restore VPS variables, release/symlink deploy and preview
  targets, safe_branch helper; adapt to use build/ output directory
- build-deploy.yml: fix deploy host, restore timestamp, use make ship
- preview.yml: fix deploy host, restore timestamp, delegate to make
  preview and safe_branch targets
