Move all git examples into ApplicationSeeder on railpack, using the
reorganized coollabsio/coolify-examples main branch, and drop the

seeded sslip.io domains (e.g. a Tailscale IP).

Provision Docker once in a prepared image and use a seed ISO for new VMs. Switch development examples to the main branch and refresh service template timestamps.
